[Clang][Driver] Recognize the AIX OBJECT_MODE environment setting
Summary:
AIX uses an environment variable called OBJECT_MODE to indicate to
utilities in the toolchain whether they should be operating in 32-bit or
64-bit mode. This patch makes the clang driver recognize the current
OBJECT_MODE setting when we are operating with an AIX target and adds a
custom diagnostic for invalid settings.
For more details about OBJECT_MODE on AIX see:
