The value is set based on the -O command-line option. It is generally useful if SIL optimization passes can check the current optimization level.
A couple of subsequent commits are going to make use of this information.

We normally report a warning when a #available() check will always be true
because of the minimum deployment target. These warnings are potentially
annoying when the developer either cannot change the minimum deployment target
from the default (as in playgrounds) or when doing so is burdensome (as for
interpreted command-line scripts, which would require passing a target triple)
-- so suppress them.
The is a updated version of the reverted r29582, which didn't check for
immediate mode properly.

The test that it's guarding is cheap enough to do all the time, and we
don't have any interesting configurations where it's not set any more.
Swift SVN r29442
That's how everything behaved anyway. Might as well make it explicit and
stop special-casing it.
I've left in compatibility for modules built with older compilers so that
people using the OS toolchains aren't immediately unable to debug their apps.
As soon as we change the module format in a more significant way, I can take
this out.

This frontend option allows one to turn off autolinking to the
specified framework. This general capability is motivated by
rdar://problem/21246363, where we need to turn off some autolinking in
our overlays due to internal vs. public SDK differences.

I was always confused by the inconsistency of -sil-print-all and the other -sil-print options.
So I thought it would be a good idea to make -sil-print-all also an llvm option.
Together with some other internal options which are only used in the pass manager.

The last remaining case was apparently @objc generic classes, which
seem to work now.
Also nuke the IRGen/unimplemented_objc_generic_class.swift test,
this is now implemented and we have other tests that test this
functionality.

Now that we are using OptionSetType for option sets, all the support for
doing things the old way can die.
Note: the fix-it that used to apply to RawOptionSetType, it seemed to me,
should still apply to OptionSetType, so I switched it over instead of
removing it.
Swift SVN r29066
Allow API providers to use escaped characters in the messages of @available()
attributes. For example, for a reference to a declaration annotated with:
@available(*, unavailable, message="use print(\"\")")
public func println() {
...
}
the message displayed to the user will be:
'println() is unavailable: use print("")'.
This also supports unicode escapes (e.g. \u{1F43C}).
A complication is that AvailableAttrs imported from clang already have their
messages unescaped, so this patch keeps track of whether an availability
attribute came from clang and, if so, does not unescape the message again when
emitting the diagnostic. We could avoid this extra book-keeping by immediately
unescaping Swift messages during parsing, keeping them in an unescaped
canonical form, and then escaping them in ASTPrinter when we print the
attributes. rdar://problem/20985357 tracks keeping AvailableAttrs messages in
a canonical form.

Swift SVN r28658
Modules occupy a weird space in the AST now: they can be treated like
types (Swift.Int), which is captured by ModuleType. They can be
treated like values for disambiguation (Swift.print), which is
captured by ModuleExpr. And we jump through hoops in various places to
store "either a module or a decl".
Start cleaning this up by transforming Module into ModuleDecl, a
TypeDecl that's implicitly created to describe a module. Subsequent
changes will start folding away the special cases (ModuleExpr ->
DeclRefExpr, name lookup results stop having a separate Module case,
etc.).
Note that the Module -> ModuleDecl typedef is there to limit the
changes needed. Much of this patch is actually dealing with the fact
that Module used to have Ctx and Name public members that now need to
be accessed via getASTContext() and getName(), respectively.

When -enable-simd-import is active, if we encounter a vector type, try to load the SIMD Swift module, and if successful, map float, double, and int vectors to SIMD.{Float,Double,Int}N types if they exist.
Swift SVN r27367
Instead of only honoring the last occurrence of -import-module, the frontend now
honors all occurrences of -import-module, making all of the modules specified on
the command line implicitly visible.
This fixes <rdar://problem/20422696>.
Swift SVN r27299
Previously, the only way to get initializers was completing after the
name of the type:
Foo#^complete_here^#
Foo(#^or_here^#
And now it will also work in unadorned expressions:
#^a_top_level_completion^#
bar(a, #^walked_into_a_bar^#
Unfortunately, not all our clients handle this well yet, so it's
protected by a language option.

Enable checking for uses of potentially unavailable APIs. There is
a frontend option to disable it: -disable-availability-checking.
This commit updates the SDK overlays with @availability() annotations for the
declarations where the overlay refers to potentially unavailable APIs. It also changes
several tests that refer to potentially unavailable APIs to use either #available()
or @availability annotations.
Swift SVN r27272
Remove the suppression of deprecation and potential unavailability diagnostics in
synthesized functions. We still suppress some explicit unavailability diagnostics -- those
in synthesized functions in synthesized functions that are lexically contained in
declarations that are themselves annotated as unavailable. For these cases, the right
solution <rdar://problem/20491640> is to not synthesize the bodies of these functions in
the first place.

We're not going to require the type parameters to be redeclared on
extensions of generic types, so take away the staging option and
diagnostic.

In particular, this is problematic when libraries are loaded dynamically, and
may have newer deployment targets than the main executable.
Swift SVN r26786
getImportedModules is the canonical way to get imports, whether private,
public, or both. This is especially true now that we have more flags
for SourceFile imports that really shouldn't be consumed by anyone
outside of SourceFile.
In this same vein, provide addImports instead of setImports, since imports
are always additive.
No visible functionality change.

...which allows "@testable import" to work with modules not compiled for
testing. This isn't generally safe, but should be fine for clients like
SourceKit which just need to have the API available and might not be able
to properly rebuild the original target for testing.
We may revisit this in the future.
Swift SVN r26629
This flag enables checking of availability (deprecation, explicit unavailability,
and potential unavailability) in synthesized functions. The flag will go away once this
checking is fully staged in.
Swift SVN r26624
Up to now we've been assuming that we have only one 32-bit target and
one 64-bit target per platform. There is a need to be able to build
armv7s for iOS, but assumptions abound in the organization of files per
architecture - tests, cmake targets, and installation.
- Build armv7s when building for iOS
- Use the actual architecture name, not blank or "/32" in all paths
related to architecture.
Testing: Clean buildbot incremental RA tests pass (requires a test
update in SourceKit as well).

This warning is temporarily going being a flag so that, once it is safe to place generic parameters on extensions of generic types, we can opt-in to update our code when it is convenient.

This flag indicates that internal APIs within the module should be made
available to client code for testing purposes. Currently does nothing.
Not ready for developer consumption yet, ergo a hidden frontend-only flag.

expectations. Instead of saying "unexpected diagnostic not produced" and
"expected diagnostic not produced", instead say "unexpected *warning* not produced".
This helps in particular when you have an expectation for a warning but got an
error with the same wording (for example).

Make this diagnostic a little nicer in other ways, too:
- Highlight the whole attribute (including the at-sign).
- Don't hardcode the string "objc".

This will be needed for split-llvm code generation.
If multiple -o options are specified and only a single output file is needed
(currently always), the last one wins. This is NFC.
