[SimplifyLibCalls] Tranform log(pow(x, y)) -> y*log(x).

This one is enabled only under -ffast-math. There are cases where the
difference between the value computed and the correct value is huge
even for ffast-math, e.g. as Steven pointed out:

x = -1, y = -4
log(pow(-1), 4) = 0
4*log(-1) = NaN

I checked what GCC does and apparently they do the same optimization
(which result in the dramatic difference). Future work might try to
make this (slightly) less worse.

Diego Novillo [Fri, 27 Nov 2015 23:14:51 +0000 (23:14 +0000)]
SamplePGO - Add initial support for inliner annotations.

This adds two thresholds to the sample profiler to affect inlining
decisions: the concept of global hotness and coldness.

Functions that have accumulated more than a certain fraction of samples at
runtime, are annotated with the InlineHint attribute. Conversely,
functions that accumulate less than a certain fraction of samples, are
annotated with the Cold attribute.

This is very similar to the hints emitted by Clang when using
instrumentation profiles.

Notice that this is a very blunt instrument. A function may have
globally collected a significant fraction of samples, but that does not
necessarily mean that every callsite for that function is hot.

Ideally, we would annotate each callsite with the samples collected at
that callsite. This way, the inliner can incorporate all these weights
into its cost model.

Once the inliner offers this functionality, we can change the hints
emitted here to a more precise per-callsite annotation. For now, this is
providing some measure of speedups with our internal benchmarks. I've
observed speedups of up to 23% (though the geo mean is about 3%). I expect
these numbers to improve as the inliner gets better annotations.

Diego Novillo [Fri, 27 Nov 2015 23:14:49 +0000 (23:14 +0000)]
SamplePGO - Fix default threshold for hot callsites.

Based on testing of internal benchmarks, I'm lowering this threshold to
a value of 0.1%.  This means that SamplePGO will respect 99.9% of the
original inline decisions when following a profile.

The performance difference is noticeable in some tests. With the
previous threshold, the speedups over baseline -O2 was about 0.63%. With
the new default, the speedups are around 3% on average.

The point of this threshold is not to do more aggressive inlining. When
an inlined callsite crosses this threshold, SamplePGO will redo the
inline decision so that it can better apply the input profile.

By respecting most original inline decisions, we can apply more of the
input profile because the shape of the code follows the profile more
closely.

In the next series, I'll be looking at adding some inline hints for the
cold callsites and for toplevel functions that are hot/cold as well.

[mips][ias] Explicitly disable IAS on tests that depend on not assembling.

Summary:
no-odd-spreg-msa.ll: This test deliberately uses an odd-numbered register
in inline assembly and expects the compiler to insert a move to an
even-numbered register.

inlineasm-operand-code.ll and inlineasm_constraint.ll:
Checks for IAS's output will be added once a matcher bug is resolved. This bug
causes the canonical output emitted by IAS to be incorrect for uimm16 constants
with the MSB set. We will still need the non-IAS checks at this point since
these tests primarily test formatting of operands.
