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.

that these passes are properly preserved.

Fix several transformation passes that claimed to preserve LoopSimplify
form but weren't.

llvm-svn: 80926

llvm-svn: 80924

LoopSimplify form, which is currently only available on Loops (and
not MachineLoops). Also, move the code out of the header file.

This makes it eaiser to use when DominatorTree information is
available.

Removed inverted flag form MaximumSpanningTree, also do not handle so much
information to MaximumSpanningTree.

with the new asmprinter.

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
...

simplifylibcalls optimization is thus valid for C++ but not C.
It's not important enough to worry about for C++ apps, so just
remove it.
