f1c0daa6a7 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

00b05492f1 Revert the addition of hasNoPointerOverflow to GEPOperator.
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

96f9a917c8 Fix http://llvm.org/bugs/show_bug.cgi?id=4583
Inline asm instructions may have additional <imp-def,kill> register operands.
These operands are not marked with a flag like the normal asm operands, so we
must not assert that there is a flag.

e507c1afaa Canonicalize bitcasts between types like <1 x i64> and i64 to
insertelement/extractelement.

I'm not entirely sure this is precisely what we want to do: should we 
prefer bitcast(insertelement) or insertelement(bitcast)?  Similarly. should we 
prefer extractelement(bitcast) or bitcast(extractelement)?

debc43cb11 Back out 76300; apparently the preference is to canonicalize the other
way (bitcast -> insert/extractelement).

It would also be possible to canonicalize the other way; does anyone 
have a preference?

e08bda67c2 Assume an inline asm might be a call, so we get
stack alignment right when it is.  This is not
ideal but conservatively correct.  Adjust a test
to compensate for changed stack offset value.

4a0d996780 Teach MachineInstr::isRegTiedToDefOperand() to correctly parse inline asm operands.
The inline asm operands must be parsed from the first flag, you cannot assume
that an immediate operand preceeding a register use operand is the flag.
PowerPC "m" operands are represented as (flag, imm, reg) triples.
isRegTiedToDefOperand() would incorrectly interpret the imm as the flag.
