[PATCH, GAS] No IT usage deprecation for ARMv8-M

[Thomas Preudhomme]

TL;DR: Committed with updated ChangeLog, is it ok for binutils 2.30?

Sorry for the delay (Christmas holidays), just committed it now. I realized the 
ChangeLog entry was incomplete so I updated it:

     2018-01-15  Thomas Preud'homme  <thomas.preudhomme@arm.com>

     gas/
         * config/tc-arm.c (it_fsm_post_encode): Do not warn if targeting M
         profile architecture or if in autodetection mode.  Clarify that
         deprecation is for performance reason and concerns Armv8-A and Armv8-R.
         * testsuite/gas/arm/armv8-ar-bad.l: Adapt to new IT deprecation warning
         message.
         * testsuite/gas/arm/armv8-ar-it-bad.l: Likewise.
         * testsuite/gas/arm/sp-pc-validations-bad-t-v8a.l: Likewise.
         * testsuite/gas/arm/udf.l: Likewise.
         * testsuite/gas/arm/udf.d: Assemble for Armv8-A explicitely.

Other than that patch is unchanged.


@Tristan: is this fix ok for Binutils 2.30? It fixes 2 mistakes in an error 
message: IT is not deprecated for Armv8-M and it is only performance deprecated 
for Armv8-A and Armv8-R.

Best regards,

Thomas
