Simon Pilgrim f6cf26bc83 [X86] Use implicit masking of SHLD/SHRD shift double instructions
Similar to the regular shift instructions, SHLD/SHRD only use the bottom bits of the shift value

Simon Pilgrim bc139df3fe [X86] Improve 64-bit shifts on 32-bit targets (PR14593)
As discussed on PR14593, this patch adds support for lowering to SHLD/SHRD from the patterns generated by DAGTypeLegalizer::ExpandShiftWithKnownAmountBit.

NAKAMURA Takumi ca3c03a167 Tweak 3 tests in llvm/test/CodeGen/X86 to add -mcpu=generic since r195383.
They failed on bdver2 buildslave.

FIXME: FileCheck-ize them.

Chandler Carruth 4177e6fff5 Convert all tests using TCL-style quoting to use shell-style quoting.
This was done through the aid of a terrible Perl creation. I will not
paste any of the horrors here. Suffice to say, it require multiple
staged rounds of replacements, state carried between, and a few
nested-construct-parsing hacks that I'm not proud of. It happens, by
luck, to be able to deal with all the TCL-quoting patterns in evidence
in the LLVM test suite.

If anyone is maintaining large out-of-tree test trees, feel free to poke
me and I'll send you the steps I used to convert things, as well as
answer any painful questions etc. IRC works best for this type of thing
I find.

Once converted, switch the LLVM lit config to use ShTests the same as
Clang. In addition to being able to delete large amounts of Python code
from 'lit', this will also simplify the entire test suite and some of
lit's architecture.

Finally, the test suite runs 33% faster on Linux now. ;]
