are st(0). These can be encoded using an opcode for storing in st(0) or using
an opcode for storing in st(i), where i can also be 0. To allow testing with
the darwin assembler and get a matching binary the opcode for storing in st(0)
is now used. To do this the same logical trick is use from the darwin assembler
in converting things like this:
fmul %st(0), %st
into this:
fmul %st(0)
by looking for the second operand being X86::ST0 for specific floating point
mnemonics then removing the second X86::ST0 operand. This also has the add
benefit to allow things like:
fmul %st(1), %st
that llvm-mc did not assemble.

a massive memory leak when using a BumpPtrAllocator in ASTContext.
Added a FIXME, as the Destroy method for TemplateArgumentList isn't getting called.
This means we will instead leak when using the MallocAllocator.

This class only supports name mangling (which is apparently used during C/ObjC
codegen). For now only the Itanium C++ ABI is supported. Patches to add a
second C++ ABI are forthcoming.

Mon Ping provided; unfortunately bugpoint failed to
reduce it, but I think it's important to have a test for
this in the suite. 8023512.

This passes lit tests, but I'll give it a go through the buildbots to smoke out
any remaining places that depend on the old SubRegIndex numbering.
Then I'll remove NumberHack entirely.

variables within blocks. We loosely follow GCC's mangling, but since
these are always internal symbols the names don't really matter. I
intend to revisit block mangling later, because GCC's mangling is
rather verbose. <rdar://problem/8015719>.

1) Suppress diagnostics as soon as we form the code-completion
token, so we don't get any error/warning spew from the early
end-of-file.
2) If we consume a code-completion token when we weren't expecting
one, go into a code-completion recovery path that produces the best
results it can based on the context that the parser is in.

Thumb2 ADD and SUB instructions: allow RSB instructions be changed to set the
condition codes, and allow RSBS instructions to be predicated.

variables should have that linkage. Otherwise, its static local
variables should have internal linkage. To avoid computing this excessively,
set a function's linkage before we emit code for it.
Previously we were assigning weak linkage to the static variables of
static inline functions in C++, with predictably terrible results. This
fixes that and also gives better linkage than 'weak' when merging is required.

- I think this can be cleaned up, since this means we may notify the consumer about the vtable twice, but I didn't see an easy fix for this without more substantial refactoring.
- Doug, please review!

there are already two spaces before the token where the : was expected,
put the : in between the spaces. This means we get it right in both
of these cases:
t.c:2:17: error: expected ':'
return a ? b c;
^
:
t.c:3:16: error: expected ':'
return a ? b c;
^
:
In the later case, the diagnostic says to insert ": ", in the former
case it says to insert ":" between the spaces. This fixes rdar://8007231
