Work around to get llvm-mingw working on aarch64

Browse Source 
It looks like llvm-mingw tool chain does not understand `.previous` asm
directive (see https://sourceware.org/binutils/docs/as/Previous.html).
As a workaround for win64 flavor (llvm-mingw toolchain) we let xlate
to emit .text instead of emitting .previous.

We also need to revisit usage of win64 flavor here in aarch64. We should
perhaps introduce a mingw flavour on aarch64 as well. win assembly
flavour should be used for microsoft assembler.

Fixes #26415
