[InstCombine] Expand the simplification of pow() into exp2()
Generalize the simplification of `pow(2.0, y)` to `pow(2.0 ** n, y)` for all
scalar and vector types.
This improvement helps some benchmarks in SPEC CPU2000 and CPU2006, such as
252.eon, 447.dealII, 453.povray. Otherwise, no significant regressions on
x86-64 or A64.
