[Mingw-w64-public] [PATCH 08/17] math: Implement the exp2() wrappers using assembly on arm64

The LLVM optimizer replaces a call to pow(2, x) back into a call to exp2(x), which ends up in an infinite loop/recursion here. To avoid the issue, one could either build exp2.c (or easier to accomplish, all of libmingwex.a) using -fno-builtin or -ffreestanding, or produce the exp2() function
