[RISCV][ISel] Fold FSGNJX idioms (#100718)
This patch folds `fmul X, (fcopysign 1.0, Y)` into `fsgnjx X, Y`. This
pattern exists in some graphics applications/math libraries.
Alive2: https://alive2.llvm.org/ce/z/epyL33
Since fpimm +1.0 is lowered to a load from constant pool after
OpLegalization, I have to introduce a new RISCVISD node FSGNJX and fold
this pattern in DAGCombine.
Closes https://github.com/dtcxzyw/llvm-opt-benchmark/issues/1072.
