[win/asan] GetInstructionSize: Support some more 2 byte instructions.

This patch adds several instructions seen when trying to run a
executable built with ASan with llvm-mingw.
(x86 and x86_64, using the git tip in llvm-project).

Also includes instructions collected by
Roman Pišl and Eric Pouech in the Wine bug reports below.
