Move the special cases for constants out of getUnknown and into

createSCEV. Also, recognize UndefValue in createSCEV.
Change getIntegerSCEV's comment to avoid mentioning FP types,
and re-implement it in terms of getConstant instead of getUnknown.

Chris recently broke llvmc with his Makefile changes (r75379). That patch made
the global change .o -> .a, which caused built-in llvmc plugins to stop working
since plugin initialization in llvmc is based on static variables not referenced
from the main executable. This patch implements auto-generated forced references
to the plugin libraries.

"The MMX_MASKMOVQ and MMX_MASKMOVQ64 instructions are labeled as MRMDestMem

instructions, which implies that there is an explicit memory operand. There is

operand is implicit, indicated by DS:EDI. This causes the table-generation code

This test only works on ppc32 if some optimization is done before
...
generating LLVM IR; it is correct in the code as written
to use 8-byte-aligned operations to copy Key in bar. Formerly
the gcc inliner was run, now it isn't. I don't think it's
possible to preserve this as a pure FE test. Adding -O2 lets
the llvm optimizers get rid of the 8-byte-aligned stores, at least.

See test. Judging from PR 1278, at the time the test was committed, the
...
generated code was apparently doing stores directly into the return value
aggregate; now, it's doing a copy from a compiler-generated static object.
That object is initialized using [4 x i8] which breaks the test. I believe
this change preserves the original point of the test.
Of course it would be better for the code to do stores directly into the
return aggregate, but that is not what happens at -O0; the llvm optimizers
seem to do that on x86 but not on ppc32, possibly because of the explicit
padding (which is unavoidable). I think it must have been being done by
a gcc optimizer pass before.
