The typedef `swift::Module` was a temporary solution that allowed
`swift::Module` to be renamed to `swift::ModuleDecl` without requiring
every single callsite to be modified.
Modify all the callsites, and get rid of the typedef.
This reverts the contents of #5778 and replaces it with a far simpler
implementation of condition resolution along with canImport. When
combined with the optimizations in #6279 we get the best of both worlds
with a performance win and a simpler implementation.
This allows script mode to pick up the current version of macOS
instead of defaulting to 10.9, making it unnecessary to write #available.
A -target flag can still override this if you're trying to write a
portable script.
The logic is a little tortured to avoid having to actually link to
Foundation.framework or libobjc.

Based off the PlaygroundTransform, this new ASTWalker leaves calls to __builtin_pc_before and __builtin_pc_after before and after a user would expect a program counter to enter a range of source code.
Changes:
* Terminate all namespaces with the correct closing comment.
* Make sure argument names in comments match the corresponding parameter name.
* Remove redundant get() calls on smart pointers.
* Prefer using "override" or "final" instead of "virtual". Remove "virtual" where appropriate.
This is a hidden option. It should be used like: -assume-single-threaded
When this function is provided, the compiler assumes that the code will be executed in the single threaded mode. It then performs certain optimizations that can benefit from it, e.g. it marks as non-atomic all reference counting instructions in the user code being compiled.
The block info block does not require an explicit abbreviation width as the
local abbreviations are internal to the block. Remove the parameter similar to
the clang change.
llvm r283043 and possibly other recent changes switch to use StringRef
instead of char* pointers. Update Swift to match. In some cases, this is
a clear improvement. It would be good to assess the impact on memory use,
particularly for the Filename component of source locations.
Note that the change to SILLocation::isNull fixes an apparent bug where
the location was treated as null when the filename was *not* null.
This will allow for semantic arc work to remain behind a flag and not affect
other in tree developers. More importantly it enables for bots to be setup with
this flag enabled.

Resilient classes are not fully implemented yet, and can cause
crashes at runtime; add a flag disabling them until the code is
done, to unblock standard library testing with resilience
enabled.
This flag switches the "effective language version" of the compiler,
at least to any version supported (as of this change: "3" or "3.0").
At the moment nothing uses it except the language version build
configuration statements (#if swift(...)) and various other places
that report, encode, or otherwise check version numbers.
In the future, it's intended as scaffolding for backwards compatibility.
Fixes SR-2582
Enables Chris's auto-apply-fixes mode for -verify: if an expected-*
annotation has the wrong message, or if the expected fix-its are
incorrect, this option will **edit the original file** to update them.
This is a tool for compiler developers only; it doesn't affect
normal diagnostic printing or normal fix-its.
Given a source location, we can find the innermost enclosing scope
that describes that source location. Introduce this operation into the
scope map, then add a testing mode where we probe the scope map at
specifi locations to see what we find. Test for:
1) Finding the right innermost enclosing scope, and
2) That we're only expanding the part of the scope map that is needed
to identify that scope.
The scope map models all of the name lookup scopes within a source
file. It can be queried by source location to find the innermost scope
that contains that source location. Then, one can follow the parent
pointers in the scope to enumerate the enclosing scopes.
The scope map itself is lazily constructed, only creating scope map
nodes when required implicitly (e.g, when searching for a particular
innermost scope) or forced for debugging purposes.
using a lazily-constructed tree that can be searched by source
location. A search within a particular source location will
This eliminates a pile of now-dead code in:
* The type checker, where we no longer have special cases for bridging conversions
* The expression ASTs, where we no longer need to distinguish bridging collection up/down casts
* SILGen, which no longer uses
Still to come is the removal of the
_(set|dictionary)Bridge(From|To)ObjectiveC(Conditional)? entrypoints
from the standard library. They're still used by some tests.
Simplify e.g., ASTContext::getBridgedToObjC(), which no longer needs
the optional return.
Eliminate the now-unused constraint kind for checking bridging to
Objective-C.
I'm slightly sad about losing the lovely code to detect
redundantly-specified defaulted arguments, but we could bring it back
later as a separate warning.
