a19f7799fb PC-relative pseudo instructions are lowered and printed directly. Any encounter 
with one in the generic printing code is an error.

670e1915c0 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.

8c2bde65f0 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.

d2cf0742a4 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.

e06344da06 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.

a43c86b354 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the

 - 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.

9dc559bdef Fix the folding of floating-point math library calls, like sin(infinity),
