Matt Arsenault 2acc7a4570 R600/SI: Fix bitcast between v2i32 and f64
This is the same problem fixed in r210664 for more types.

The test passes without this fix. For some reason
I'm only hitting this when creating selects lowered
to v2i32 selects.

Matt Arsenault 364a6747aa R600/SI: Use v_cvt_f32_ubyte* instructions
This eliminates extra extract instructions when loading an i8 vector to
a float vector.

Matt Arsenault 064c206d23 R600/SI: Fix selection failure on scalar_to_vector
There seem to be only 2 places that produce these,
and it's kind of tricky to hit them.

Also fixes failure to bitcast between i64 and v2f32,
although this for some reason wasn't actually broken in the
simple bitcast testcase, but did in the scalar_to_vector one.

Tom Stellard 70f13dba15 R600/SI: Use -verify-machineinstrs for most tests
We can't enable the verifier for tests with SI_IF and SI_ELSE, because
these instructions are always followed by a COPY which copies their
result to the next basic block.  This violates the machine verifier's
rule that non-terminators can not folow terminators.
