TableGen had been nicely generating code to print a number of instructions using
shorter aliases (and PowerPC has plenty of short mnemonics), but we were not
calling it. For some of the aliases we support in the parser, TableGen can't
infer the "inverse" alias relationship, so there is still more to do.
Thus, after some hours of updating test cases...

Summary:
Currently fast-isel-abort will only abort for regular instructions,
and just warn for function calls, terminators, function arguments.
There is already fast-isel-abort-args but nothing for calls and
terminators.
This change turns the fast-isel-abort options into an integer option,
so that multiple levels of strictness can be defined.
This will help no being surprised when the "abort" option indeed does
not abort, and enables the possibility to write test that verifies
that no intrinsics are forgotten by fast-isel.

Patch by Bill Seurer; some comment formatting changes by me.
There are a few PowerPC test cases for FastISel support that currently
fail with VSX support enabled. The temporary workaround under
discussion in http://reviews.llvm.org/D5362 helps, but the tests still
fail because they specify -fast-isel-abort, and the VSX workaround
punts back to SelectionDAG. We have plans to fix FastISel permanently
for VSX, but until that's in place these tests are preventing us from
enabling VSX by default. Therefore we are adding -mattr=-vsx to these
tests until the full support is ready.

Mostly trivial patch adding support for compares. The meat of the
work was added with the branch support.
