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.

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.

The inline asm operands must be parsed from the first flag, you cannot assume

PowerPC "m" operands are represented as (flag, imm, reg) triples.
