0b34068b2b change selectiondag to add the sign extended versions of immediate operands
to instructions instead of zero extended ones.  This makes the asmprinter
print signed values more consistently.  This apparently only really affects
the X86 backend.

2e9f3b2865 fix PR4767, a crash because fp stackifier visited blocks in
depth first order, so it wouldn't process unreachable blocks.
When compiling at -O0, late dead block elimination isn't done
and the bad instructions got to isel.

1d2e18b27c If we've pushed registers onto the stack, but aren't adjusting the stack pointer
(i.e., there are no local variables and stuff), we still need to output FDE

985c62a61e Fixed a few problems with vector shifts
- when transforming a vector shift of a non-immediate scalar shift amount, zero
    extend the i32 shift amount to i64 since the vector shift reads 64 bits
  - when transforming i16 vectors to use a vector shift, zero extend i16 shift amount
  - improve the code quality in some cases when transforming vectors to use a vector shift

c50ad41cc5 Add a -disable-16bit flag and associated support for experimenting with
disabling the use of 16-bit operations on x86. This doesn't yet work for
inline asms with 16-bit constraints, vectors with 16-bit elements,
trampoline code, and perhaps other obscurities, but it's enough to try
some experiments.

5f29771ea2 Removed the non-target independent AsmToken::Register enum constant
from MCAsmLexer.h in preparation of supporting other targets.  Changed the
X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking
for AsmToken::Percent when parsing in places that used AsmToken::Register.
Then changed X86ATTAsmParser::ParseRegister to parse out registers as an
AsmToken::Percent followed by an AsmToken::Identifier.

d7cc632fcf Implement support for X86II::MO_GOT_ABSOLUTE_ADDRESS. We get very
different formatting from the old asmprinter, but it should be 
semantically the same.  We used to get:

	popl	%eax
	addl	$_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$6.$piclabel], %eax
...

Now we get:

	popl	%eax
.Lpicbaseref6:
	addl	$(_GLOBAL_OFFSET_TABLE_ + (.Lpicbaseref6 - .Lllvm$6.$piclabel)), %eax
...

1c6706b750 Added opaque 32-, 48-, and 80-bit memory operand types to the X86
instruction tables to support segmented addressing (and other objects
of obscure type).
Modified the X86 assembly printers to handle these new operand types.
Added JMP and CALL instructions that use segmented addresses.
