[Linker] Remove warning when linking ARM and Thumb IR modules.
Summary:
This patch updates Triple::isCompatibleWith to make armxx and thumbxx
triples compatible, as long as the subarch, vendor, os, envorionment and
object format match. Thumb/ARM code generation should be controlled
using the thumb-mode per-function target feature rather than by the
triple to allow mixing Thumb and ARM functions.
D33448 updates Clang's codegen to add thumb-mode for all functions with
armxx or thumbxx triples.
