comments (fast isel, X86). This doesn't seem
to break any functionality, but will introduce
cases where -g affects the generated code. I'll
be fixing that.

idea, but unfortunately necessary.
- Default to using 4-bytes for the LSDA pointer encoding to agree with the
encoded value in the CIE.

as it emits code. Switch .globl directives to use OutStreamer instead of
doing it textually (in x86)

remove it and change all the code that prints MCSymbols to use
<< instead, which is much simpler and cleaner.

and add an explicit ForcePrivate argument.
Switch FunctionEHFrameInfo to be MCSymbol based instead of string based.

The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.

Note that the code wasn't calling DecorateCygMingName
when emitting the ".ascii -export" stuff at the end of
file for DLLExported functions. I don't know if it should
or not, but I'm preserving behavior.

target-dependent memory address representation in it.
Restore X86 printing of DEBUG_VALUE; lowering is
done in X86RegisterInfo using the normal algorithm.

to return range information for subexpressions. Use this to
provide range info for several new X86Operands.

FrameIndexes should be lowered, but the same way as
everything else (target dependent) rather than in a
special hacked way. The lowering needs to be done
for eventual purposes of Dwarf generation.

the new ParseInstruction method just parses and returns a list of
target operands. A new MatchInstruction interface is used to
turn the operand list into an MCInst.
This requires new/deleting all the operands, but it also gives
targets the ability to use polymorphic operands if they want to.

instead of returning it in an std::string. Based on this change:
1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
prefixes, not use temporary std::strings, and to avoid other crimes.

For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

to not touch Cygwin: the change caused llvm-gcc build failures due to
long double getting the wrong size. Patch by Aaron Gray.

instruction is copy like where the source and destination registers can
overlap. This is to be used by the coalescable to coalesce the source and
destination registers of instructions like X86::MOVSX64rr32. Apparently
some crazy people believe the coalescer is too simple.
