[PowerPC] Don't use a non-allocatable register to implement the 'cc' alias

GCC accepts 'cc' as an alias for 'cr0', and we need to do the same when

non-allocatable register, named 'cc', that was listed as an alias of 'cr0', but
the infrastructure does not seem to support this properly (neither the register
allocator nor the scheduler properly accounts for the alias). Instead, we can
just process this as a naming alias inside of the inline asm
constraint-processing code, so we'll do that instead.

There are two regression tests, one where the post-RA scheduler did the wrong
thing with the non-allocatable alias, and one where the register allocator did
the wrong thing. Fixes PR21742.

InstrProf: An intrinsic and lowering for instrumentation based profiling

counters for profiling, as in clang's ``-fprofile-instr-generate``.

Doing the instrumentation this way opens some doors in terms of
improving the counter performance. For example, this will make it
simple to experiment with alternate lowering strategies, and allows us

[X86] Improved lowering of packed v8i16 vector shifts by non-constant count.

Before this patch, the backend sub-optimally expanded the non-constant shift
count of a v8i16 shift into a sequence of two 'movd' plus 'movzwl'.

With this patch the backend checks if the target features sse4.1. If so, then
it lets the shuffle legalizer deal with the expansion of the shift amount.

Example:
;;
define <8 x i16> @test(<8 x i16> %A, <8 x i16> %B) {
  %shamt = shufflevector <8 x i16> %B, <8 x i16> undef, <8 x i32> zeroinitializer
  %shl = shl <8 x i16> %A, %shamt
  ret <8 x i16> %shl
}
;;

Before (with -mattr=+avx):
  vmovd  %xmm1, %eax
  movzwl  %ax, %eax
  vmovd  %eax, %xmm1

SelectionDAG switch lowering: Replace unreachable default with most popular case.

This can significantly reduce the size of the switch, allowing for more
efficient lowering.

I also worked with the idea of exploiting unreachable defaults by
omitting the range check for jump tables, but always ended up with a
non-neglible binary size increase. It might be worth looking into some more.

SimplifyCFG currently does this transformation, but I'm working towards changing
that so we can optimize harder based on unreachable defaults.
