Owen Anderson b92b13d8a0 Invert the logic of reachesChainWithoutSideEffects(). What we want to check is that there is 
NO path to the destination containing side effects, not that SOME path contains no side effects.
In  practice, this only manifests with CombinerAA enabled, because otherwise the chain has little
to no branching, so "any" is effectively equivalent to "all".

thumb with floating point.

Jim Grosbach af5d63583e factor out a simple helper function to create a label for PC-relative 
instructions (PICADD, PICLDR, et.al.)

Jim Grosbach 8a5a6a6c1e PC-relative pseudo instructions are lowered and printed directly. Any encounter 
with one in the generic printing code is an error.

Bob Wilson cb6db98897 Add target-specific DAG combiner for BUILD_VECTOR and VMOVRRD. An i64 
value should be in GPRs when it's going to be used as a scalar, and we use
VMOVRRD to make that happen, but if the value is converted back to a vector
we need to fold to a simple bit_convert.  Radar 8407927.

and shift instructions on ARM. Update the tests to match.

Evan Cheng e53ab6dffc Teach machine sink to 
1) Do forward copy propagation. This makes it easier to estimate the cost of the
   instruction being sunk.
2) Break critical edges on demand, including cases where the value is used by
   PHI nodes.
Critical edge splitting is not yet enabled by default.

Jim Grosbach 6d800f88da Update tests to handle MC-inst instruction printing of shift operations. The 
legacy asm printer uses instructions of the form, "mov r0, r0, lsl #3", while
the MC-instruction printer uses the form "lsl r0, r0, #3". The latter mnemonic
is correct and preferred according the ARM documentation (A8.6.98). The former
are pseudo-instructions for the latter.

Duncan Sands 922563cc6d Some of the tests build an executable with llvm-gcc. For this to work, llvm-gcc 
needs to find some libraries, which may require searching the directories given
by LIBRARY_PATH on curiously configured systems.  So pass on LIBRARY_PATH.

Daniel Dunbar 55f16678e4 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the 
expression to include the modifier.
 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.
