Michael Kitzan c4e589b795 [GISel] Add new combines for unary FP instrs with constant operand ...

https://reviews.llvm.org/D86393

Patch adds five new `GICombinerRules`, one for each of the following unary
FP instrs: `G_FNEG`, `G_FABS`, `G_FPTRUNC`, `G_FSQRT`, and `G_FLOG2`. The
combine rules perform the FP operation on the constant operand and replace
the original instr with the result. Patch additionally adds new combiner
tests for the AArch64 target to test these new combiner rules.
