tools will continue to get it without any changes.

Instead of doing a RPO traversal of the whole function remember the blocks
containing gathers (typically <= 2) and scan them in dominator-first order.

The actual CSE is still quadratic, but I'm not confident that adding a
scoped hash table here is worth it as we're only looking at the generated
instructions and not arbitrary code.

This reverts commit r193356, it caused PR17781.

A reduced test case covering this regression has been added to the test suite.

Llvm_target tests did not check for return values. This actually
caused them to miss a bug.

This adds an SimplifyLibCalls case which converts the special __sinpi and
__cospi (float & double variants) into a __sincospi_stret where appropriate to
remove duplicated work.

When LLVM is embedded in a larger application, it's not OK for LLVM to intercept crashes.  LLVM already has 
the ability to disable this functionality.  This patch exposes it via the C API.

Doing this with a hash map doesn't change behavior and avoids calling
isIdenticalTo O(n^2) times. This should probably eventually move into a utility
class shared with EarlyCSE and the limited CSE in the SLPVectorizer.

There is still a long way to go for llvm-nm, but at least we now match
nm's letter output in the cases we test for.

- When selecting BLEND from vselect, the operands need swapping as due to the
  difference between vselect and SSE/AVX's BLEND insn

Added -o option to llvm-cov. If no output file is specified, it defaults
to STDOUT.
