[mips] Manually replace JAL pseudo-instructions with their JALR equivalent, instead of using InstAlias.

Summary:
This is needed by the .cprestore assembler directive.

This directive needs to be able to insert an LW instruction after every JALR replacement of a JAL pseudo-instruction
(and never after a JALR which has NOT been a result of a pseudo-instruction replacement).

The problem with using InstAlias for these is that after it replaces the pseudo-instruction, we can't find out if the resulting JALR instruction
was generated by an InstAlias or not, so we don't know whether or not to insert our LW instruction.

By replacing it manually, we know when the pseudo-instruction replacement happens and we can insert the LW instruction correctly.

Change a very hot piece of code in TableGen's register unit computations to use bit vectors rather than arrays.

For target descriptions with very large and very dense register files, TableGen
can take an extremely long time to run.  This change makes a dent in that (~15%
in my measurements) by accelerating the single hottest operation with better data
structures.

I believe there's still a lot of room to make this even faster with more global
changes that require replacing some of the existing datastructures in this area
with bit vectors, but that's a more involved change and I wanted to get this
simpler improvement in first.

Move the target specific test case arbitrary-induction-step.ll to test/Transforms/LoopVectorize/AArch64 folder.

llvm-svn: 227561

Previously, only -1 and +1 step values are supported for induction variables. This patch extends LV to support
arbitrary constant steps.
Initial patch by Alexey Volkov. Some bug fixes are added in the following version.

accumulateAndSortLibcalls in LTOCodeGenerator.cpp collects names of runtime
library functions which are used to identify user-defined functions that should
be protected. Previously, this function would only scan the TargetLowering
object belonging to the "main" subtarget for the library function names. This
commit changes it to scan all per-function subtargets.

In the large code model, we now put __chkstk in %r11 before calling it.

Refactor the code so that we only do this once. Simplify things by using
__chkstk_ms instead of __chkstk on cygming. We already use that symbol
in the prolog emission, and it simplifies our logic.

between the linker's TLS optimizations and Clang's TLS code generation.

For now, Clang has been changed to disable linker TLS optimizations
until it (and LLVM more generally) are emitting TLS code sequences
compatible with the old bugs found in the linkers. That's a better fix
to handle bootstrapping on that platform.
