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.

change TLS_ADDR lowering to lower to a real mem operand, instead of matching as
a global with that gets printed with the :mem modifier. All operands to lea's
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this. There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).
This also makes the use of EBX explicit in the operand list in the 32-bit,
