Aditya Nandakumar 2144a3bdbb [GISel] Add combiners for G_INTTOPTR and G_PTRTOINT ...

https://reviews.llvm.org/D84909

Patch adds two new GICombinerRules, one for G_INTTOPTR and one for
G_PTRTOINT. The G_INTTOPTR elides ptr2int(int2ptr(x)) to a copy of x, if
the cast is within the same address space. The G_PTRTOINT elides
int2ptr(ptr2int(x)) to a copy of x. Patch additionally adds new combiner
tests for the AArch64 target to test these new combiner rules.
