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.

6ea9973a0b don't call getOffset() on jump tables, this fixes three failing olden benchmarks

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
...

functionality change other than unbreaking my previous patch.

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.

9a220088ac Clean up LSDA name generation and use for SJLJ exception handling. This 
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.

Objective C++ code could generate function names that broke the previous
scheme. This fixes that.
