x86: Disable AMX-TF32 by default

AMX-TF32 got depublished in ISE062. Just like AMX-TRANSPOSE, we
will keep the AMX-TF32 support for now in case there are x86 vendors
want to utilize the feature. AMX-TF32 will not show up on any
Intel/AMD hardware. Also in foreseeable future, no hardware will
support AMX-TF32, we will disable it by default. For testcases,
we will simply add .arch .amx_tf32 to keep the original test
intuition.

gas/ChangeLog:

        * testsuite/gas/i386/x86-64-amx-tf32.s: Add .amx_tf32.
        * testsuite/gas/i386/x86-64-amx-tf32-inval.s: Ditto.
        * testsuite/gas/i386/x86-64-amx-transpose.s: Ditto.
        * testsuite/gas/i386/x86-64-amx-transpose-inval.s: Ditto.
        * testsuite/gas/i386/x86-64-amx-tf32-inval.l: Adjust line
	number.
        * testsuite/gas/i386/x86-64-amx-transpose-inval.l: Ditto.

opcodes/ChangeLog:

        * i386-gen.c: Disable AMX-TF32 by default.
        * i386-init.h: Regenerated.
