When a virtual register is live across a call, limit the search space to
call-preserved registers.

Creating the isPredicated TSFlag enables the code
to use the property defined in the instruction format
instead of using a large switch statement.

Build an ordered vector of register mask operands (i.e., calls) when
computing live intervals. Provide a checkRegMaskInterference() function
that computes a bit mask of usable registers for a live range.

This is a quick way of determining of a live range crosses any calls,
and restricting it to the callee saved registers if it does.
Previously, we had to discover call clobbers for each candidate register
independently.

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

Remove GCC builtins for vpermilp* intrinsics as clang no longer needs them. Custom lower the intrinsics to the vpermilp target specific node and remove intrinsic patterns.

This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.
