Fix PR19144: Incorrect offset generated for int-to-fp conversion at -O0.

When converting a signed 32-bit integer to double-precision floating point on
hardware without a lfiwax instruction, we have to instead use a lfd followed
by fcfid.  We were erroneously offsetting the address by 4 bytes in
preparation for either a lfiwax or lfiwzx when generating the lfd.  This fixes
that silly error.

This was not caught in the test suite since the conversion tests were run with
-mcpu=pwr7, which implies availability of lfiwax.  I've added another test
case for older hardware that checks the code we expect in the absence of
lfiwax and other flavors of fcfid.  There are fewer tests in this test case
because we punt to DAG selection in more cases on older hardware.  (We must
generate complex fiddly sequences in those cases, and there is marginal
benefit in duplicating that logic in fast-isel.)

Tolerate unmangled names in sample profiles.

Summary:
The compiler does not always generate linkage names. If a function
has been inlined and its body elided, its linkage name may not be
generated.

When the binary executes, the profiler will use its unmangled name
when attributing samples. This results in unmangled names in the
input profile.

We are currently failing hard when this happens. However, in this case
all that happens is that we fail to attribute samples to the inlined
function. While this means fewer optimization opportunities, it should
not cause a compilation failure.

This patch accepts all valid function names, regardless of whether
they were mangled or not.

Dan Gohman [Mon, 17 Mar 2014 19:57:04 +0000 (19:57 +0000)]
Use range metadata instead of introducing selects.

When GlobalOpt has determined that a GlobalVariable only ever has two values,
it would convert the GlobalVariable to a boolean, and introduce SelectInsts
at every load, to choose between the two possible values. These SelectInsts
introduce overhead and other unpleasantness.

This patch makes GlobalOpt just add range metadata to loads from such
GlobalVariables instead. This enables the same main optimization (as seen in
test/Transforms/GlobalOpt/integer-bool.ll), without introducing selects.

The main downside is that it doesn't get the memory savings of shrinking such
GlobalVariables, but this is expected to be negligible.

[VectorLegalizer/X86] Don't unvectorize fp_to_uint for v8f32->v8i16

Rather than LegalizeAction::Expand, this needs LegalizeAction::Promote to get
promoted to fp_to_sint v8f32->v8i32.  This is a legal operation on AVX.

For that to work properly, we also need to teach the legalizer about the
specific promotion required here.  The default vector promotion uses
bitcasting to a vector type of the same total size.  We want to promote the
vector element type, effectively widening the operation and then truncating
the result.  This is analogous to the current logic of how int_to_fp is
promoted.

The change also factors out some code from the int_to_fp promotion code to
ValueType::widenIntegerVectorElementType.  This is now shared between
int_to_fp and fp_to_int.

There is no longer need for the custom lowering of fp_to_sint f32->v8i16 in
X86.  It can now go through the new target-independent fp_to_*int promotion
logic.

I also checked that no other target uses Promote for these ops yet, so there
shouldn't be any unexpected change in behavior.
