253aa4d192 Add llvm::Metadata to manage metadata used in a context. 
This interface will be used to attach metadata with an instruction.

41b1d4288a Fixed some problems with the logic of parsing line comments by adding 
isAtStartOfComment and using that instead in two places where a loop
to check if the char was in MAI.getCommentString().

c7e3d84790 Change FoldPHIArgBinOpIntoPHI to decline folding if it would introduce two

e9d86c0126 Do not try and sink a load whose chain result has more than one use, when 
trying to create RMW opportunities in the x86 backend.  This can cause a 
cycle to appear in the graph, since the other uses may eventually feed into
the TokenFactor we are sinking the load below.

a3e93882f3 Added the definitions for one-bit left shifts to 
the Intel instruction tables.

The patterns will stay blank because ADD reg, reg
is faster, but having the encoding available is
useful for the disassembler.

77638f25b1 Don't sink gep operators through phi nodes if the result would require 
more than one phi, since that leads to higher register pressure on
entry to the phi. This is especially problematic when the phi is in
a loop header, as it increases register pressure throughout the loop.

7b52d90c9e Big change #1 for personality function references: 
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

296ed7d1e1 Added a variety of floating-point and SSE instructions. 
All of these do not have patterns (they're for the
disassembler).

Many of the floating-point instructions will probably
be rolled into definitions that have patterns, and may
eventually be superseded by mdefs.  So I put them
together and left a comment.

GlobalVariable*.

91c3b33e33 eliminate the PPC backend's implementation of EmitExternalGlobal 
and use PersonalityPrefix/Suffix to achieve the same effect (like
the x86 backend).

This changes the code generated for ppc static mode, but guess what,
we were generating this before:

	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
	.long	___gxx_personality_v0-.                     ; Personality

which is not correct! (it is not an 'indirect' reference).
