simply use the getParser method from MCAsmParserExtension, working through the
MCAsmParser interface. There's no longer a need to overload that method to
cast it to the concrete AsmParser.

llvm-svn: 172491

This finally allows AsmParser to no longer list GenericAsmParser as a friend.
All member vars directly accessed by GenericAsmParser have been properly
encapsulated and exposed through the MCAsmParser interface. This reduces the
coupling between AsmParser and GenericAsmParser.

The included test case is derived from one of the GCC compatibility tests.
The problem arises after the selection DAG has been converted to type-legalized
form.  The combiner first sees a 64-bit load that can be converted into a
pre-increment form.  The original load feeds into a SRL that isolates the
upper 32 bits of the loaded doubleword.  This looks like an opportunity for
DAGCombiner::ReduceLoadWidth() to replace the 64-bit load with a 32-bit load.

However, this transformation is not valid, as the replacement load is not
a pre-increment load.  The pre-increment load produces an extra result,
which feeds a subsequent add instruction.  The replacement load only has
one result value, and this value is propagated to all uses of the pre-
increment load, including the add.  Because the add is looking for the
second result value as its operand, it ends up attempting to add a constant
to a token chain, resulting in a crash.

So the patch simply disables this transformation for any load with more than
two result values.

Now that it behaves itself in terms of streamer independence (r172450), this
method can be moved to MCAsmParser to be available to all extensions,
overriding, etc.
