[PowerPC] Implement some additional TLI callbacks
Add implementations of:
bool isLegalICmpImmediate(int64_t Imm) const
bool isLegalAddImmediate(int64_t Imm) const
bool isTruncateFree(Type *Ty1, Type *Ty2) const
bool isTruncateFree(EVT VT1, EVT VT2) const
bool shouldConvertConstantLoadToIntImm(const APInt &Imm, Type *Ty) const
Unfortunately, this regresses counter-register-based loop formation because
some of the loops now end up in forms were SE cannot compute loop counts.
However, nevertheless, the test-suite results favor committing:
SingleSource/Benchmarks/BenchmarkGame/puzzle: 26% speedup
MultiSource/Benchmarks/FreeBench/analyzer/analyzer: 21% speedup
MultiSource/Benchmarks/MiBench/automotive-susan/automotive-susan: 20% speedup
SingleSource/Benchmarks/Polybench/linear-algebra/kernels/trisolv/trisolv: 19% speedup
SingleSource/Benchmarks/Polybench/linear-algebra/kernels/gesummv/gesummv: 15% speedup
MultiSource/Benchmarks/FreeBench/pcompress2/pcompress2: 2% speedup
MultiSource/Benchmarks/VersaBench/bmm/bmm: 26% slowdown
