[RyuJIT][arm64] Recognize madd/msub

[EgorBo]

Currently for a * b + c; (integers) we emit:

  mul     w0, w0, w1
  add     w0, w0, w2

but C++ compilers emit: madd (or msub): https://godbolt.org/z/PMhq9G

Shouldn't be difficult to implement, a very simple implementation: EgorBo@8b7be3f (perhaps, it's better to introduce a new node for it since we might want to also recognize fmadd (for fp) in future in a sort of an "unsafe" math mode.
