[PowerPC] Emit scalar fp min/max instructions
VSX provides floating point minimum and maximum instructions that conform
to IEEE semantics. This legalizes the respective nodes and emits VSX code
for them. Furthermore, on Power9 cores we have xsmaxcdp and xsmincdp
instructions that conform to language semantics for the conditional operator
even in the presence of NaNs.

[PowerPC] Add profitablilty check for conversion to mtctr loops
Add profitability checks for modifying counted loops to use the mtctr instruction.
The latency of mtctr is only justified if there are more than 4 comparisons that
will be removed as a result. Usually counted loops are formed relatively early
and before unrolling, so most low trip count loops often don't survive. However
we want to ensure that if they do, we do not mistakenly update them to mtctr loops.
Use CodeMetrics to ensure we are only doing this for small loops with small trip counts.

[PowerPC] Map max/minnum intrinsics and fmax/fmin to ISD nodes for CTR-based loop legality
Intrinsic::maxnum and Intrinsic::minnum, along with the associated libc
function calls (fmax[f], etc.) generally map to function calls after lowering.
For some vector types with QPX at least, however, we can legally lower these,
and we don't need to prohibit CTR-based loops on their account.
It turned out, however, that the logic that checked the opcodes associated with
intrinsics was broken (it would set the Opcode variable, but that variable was
later checked only if set for some otherwise-external function call.
This fixes the latter problem and adds the FMAX/MINNUM mappings.
