Craig Topper 07b6d3de1b [X86] Add new variadic avx512 compress/expand intrinsics that use vXi1 types for the mask argument. 
Custom lower the builtins to these intrinsics. This enables the middle end to optimize out bitcasts for the masks.

Craig Topper cd9e232a4d Recommit r350555 "[X86] Use funnel shift intrinsics for the VBMI2 vshld/vshrd builtins." 
The MSVC limit hit in AutoUpgrade.cpp has been worked around for now.

Craig Topper 33c9088783 Revert r350555 "[X86] Use funnel shift intrinsics for the VBMI2 vshld/vshrd builtins." 
Had to revert the LLVM patch this depends on to fix a MSVC compiler limit in AutoUpgrade.cpp

Craig Topper b4f7c5f0fd [X86] Update VBMI2 vshld/vshrd tests to use an immediate that doesn't require a modulo. 
Planning to replace these with funnel shift intrinsics which would mask out the extra bits. This will help minimize test diffs.

Craig Topper 2527c378c6 [X86] Remove masking from avx512vbmi2 concat and shift by immediate builtins. Use select builtins instead.

Craig Topper 3cce6a7ed9 [X86] Use target independent masked expandload and compressstore intrinsics to implement expandload/compressstore builtins. 
Summary: We've had these target independent intrinsics for at least a year and a half. Looks like they do exactly what we need here and the backend already supports them.
