[PowerPC] Make r2 allocatable on PPC64/ELF for some leaf functions

that we can depend on it being there. However, for leaf functions, and
specifically those leaf functions that don't do any TOC access of their own

The most important change here is that this pushes the function we need

[PM] Port TTI to the new pass manager, introducing a TargetIRAnalysis to
produce it.
This adds a function to the TargetMachine that produces this analysis
via a callback for each function. This in turn faves the way to produce
a *different* TTI per-function with the correct subtarget cached.
I've also done the necessary wiring in the opt tool to thread the target
machine down and make it available to the pass registry so that we can
construct this analysis from a target machine when available.

[NVPTX] Emit .pragma "nounroll" for loops marked with nounroll
Summary:
CUDA driver can unroll loops when jit-compiling PTX. To prevent CUDA
driver from unrolling a loop marked with llvm.loop.unroll.disable is not
unrolled by CUDA driver, we need to emit .pragma "nounroll" at the
header of that loop.
This patch also extracts getting unroll metadata from loop ID metadata
into a shared helper function.
