FIXME: There is still work left to do here, the testcase should work even with -flimit-debug-info.

This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want.

to provide proper overloading, and also prevents mangling conflicts with
template arguments of protocol-qualified type.
This is a non-backward-compatible mangling change, but per discussion with
John, the benefits outweigh this cost.

If we have something like
@class NewImage;
@compatibility_alias OldImage NewImage;
@class OldImage;
the lookup for 'OldImage' will return the 'NewImage' decl ("@class NewImage").
In such a case, when creating the decl for "@class OldImage" use the real declaration name ("NewImage"),
instead of the alias one ("OldImage"), otherwise we will break IdentifierResolver and redecls-chain invariants.

did a manual "target modules add", it would be a file path. If the kext bundle lookup fails,
fall back to calling PlatformDarwin's GetSharedModule which will handle a file path correctly.

Said assert assumes that ADDC will always have a glue node as its second
argument and is checked before we even know that we are actually performing the
relevant MLAL optimization. This is incorrect since on ARM we *CAN* codegen ADDC
with a use list based second argument. Thus to have both effects, I converted
the assert to a conditional check which if it fails we do not perform the
optimization.
In terms of tests I can not produce an ADDC from the IR level until I get in my
multiprecision optimization patch which is forthcoming. The tests for said patch
would cause this assert to fail implying that said tests will provide the
relevant tests.

I have had several people ask me about why this builtin was not available in
clang (since it seems like a logical conclusion). This patch implements said
builtins.
Relevant tests are included as well. I also updated the Clang language extension reference.

"When assembling to the ARM instruction set, the .N qualifier produces
an assembler error and the .W qualifier has no effect."
In the pre-matcher handler in the asm parser the ".w" (wide) qualifier
when in ARM mode is now discarded. And an error message is now
produced when the ".n" (narrow) qualifier is used in ARM mode.
Test cases for these were added.

This allows optmizations to kick in more easily.
Fix some test cases so that they remain meaningful (i.e., not completely dead
coded) when optimizations apply.

When producing objects that are abi compliant we are
marking neither the object file nor the assembly file
correctly and thus generate warnings.
We need to set the EF_CPIC flag in the ELF header when
generating direct object.
Note that the warning is only generated when compiling without PIC.
When compiling with clang the warning will be suppressed by supplying:
-Wa,-mno-shared -Wa,-call_nonpic
Also the following directive should also be added:
.option pic0
when compiling without PIC, This eliminates the need for supplying:
-mno-shared -call_nonpic
on the assembler command line.

Modifying our data formatters matching algorithm to ensure that "const X*" is treated as equivalent to "X*"
Also, a couple improvements to the "lldb types" logging

For decoding, keep the current behavior of always decoding these as their REP
versions. In the future, this could be improved to recognize the cases where
these behave as XACQUIRE and XRELEASE and decode them as such.

The backend will now use the generic 'returned' attribute to form tail calls where possible, as well as avoid save-restores of 'this' in some cases (specifically the cases that matter for the ARM C++ ABI).
This patch also reverts a prior front-end only partial implementation of these optimizations, since it's no longer required.
