Assumes that (is_clang = false && is_win) => Windows native (MSVC).
Cross-compile builds will use clang and not the native tools and thus
not fall into this category.
This CL adds x86 and x64 MASM trampolines that can be used with the
native Windows toolchain (ml.exe, ml64.exe), when using is_clang =
false.
This reverts commit 8e4a5e973e.
