[Patch ARM] Fix build attributes for armv8-a in case of assembler files that contain no directives.
There is currently a problem in the way in which we produce
build attributes for simple assembler files that have armv8-a
instructions.
In these case we need to generate TAG_ISA_THUMB_Use to be Thumb-2
and set the architecture profile to be 'A' rather than not
setting architecture profile to be 'A' and setting TAG_ISA_THUMB_Use
to be Thumb-1.
This is a pre-requisite for any v8-m patches that have been posted.
arm-none-eabi gas testsuite run. no regressions.
