type, so we emit them. Add mangler (and demangler) support for these.
Enhance our testcase to check to make sure that stores within these
specifiers are direct, they don't cause recursive infinite loops.
John, I picked w/W for the mangling letters, let me know if this is ok.

This activates a special mode where code is also generated for input files.
We don't really care about this for -i mode, but it makes -repl mode a bit
nicer.

Edge SILFunction one step closer to independence from SILFunctionType context by taking the generic param list as a separate constructor parameter, and serializing those params alongside the function record. For now we still pass in the context params from the SILFunctionType in most cases, because the logic for finding the generic params tends to be entangled in type lowering, but this pushes the problem up a step.
Thanks Jordan for helping work out the serialization changes needed.

-emit-llvm in Clang is a modifier on the -S and -c actions. In Swift,
it's a separate action equivalent to "-S -emit-llvm". Be less ambiguous.
Part of the migration to the new driver.

With that change, all calls to adjustSelfTypeForMember are in the
argument list of coerceObjectArgumentToType. Instead of doing this,
just call adjustSelfTypeForMember from coerceObjectArgumentToType
instead.

variable are direct in init/destructor and in the didSet/willSet specifiers
themselves (to avoid infinite loops in reassignments).
Also, teach adjustSelfTypeForMember to handle direct accesses properly,
and move isImplicitDirectMemberReference early enough that it can find out
about inferred directness.

Previously it would create a new module if one was not passed in. There
are no uses where we do not or cannot provide a module, so it seems
reasonable to make the interface consistently require a module.

Casting in between different types will not affect a pointers reference count.
This increases the number of increment/decrement pairs we remove from 1720 ->
2040 pairs.

When SWIFT_OPTIMIZED is not set, add a little extra memory debugging,
which doesn't seem to slow anything down noticeably and can be disabled
as needed.
This change only affects the CMake build because that's the only place
where SWIFT_RUNTIME_CLOBBER_FREED_OBJECTS is supported already. We may
want to extend this to the Makefile build.

Adjusted how this option is handled: it is now set in IRGenOptions. If set,
this prevents the relevant passes from being added at all, instead of making
them no-ops.

Since we type-check local variables in statement order in a function, but
resolve names on a whole-scope basis, we can end up with a name that refers
to a local variable before its declaration has been reached. If this happens,
the variable won't have a type.
Checking this correctly may require comparing the order of statements in a
syntactic scope, but for now, just emit an error message if a reference
ever resolves to a variable without a type. (Note that UnqualifiedLookup
will have already tried to validate the decl, so if it's a global we just
haven't seen yet there's not a problem.)
Unfortunately, we won't get this right for top-level variables in script
source files, since those are still stored at global context and can be
validated on demand. They're never uninitialized, but zero-initialization
may not be valid for all global kinds.

We add two records in sil_block to specify a witness table record and a method
entry record. Out of the four entry types, only "Method" is handled in this
commit.
Two records are also added to sil_index_block to search for a specific witness
table given a unique identifier. The interface lookupWitnessTable is not
implemented yet.
Right now, we serialize a witness table only when sil-serialize-all is on and
deserialize all witness tables in the module when sil-link-all is on.

Using a linked list for metadata caches is pretty lame. Pull in llvm::DenseMap and hash_combine_range and use them to index instantiated metadata.

This pass attempts to remove alloc_ref and everything that uses the alloc_ref
if:
1. The alloc_ref has a destructor which we can very does not have escaping side
effects.
2. The alloc_ref does not have any non-trivial uses that are not stores.
It reduces ObjInst on my cpu from 10206922128 ns to 46 ns (i.e. nothing).
