x86: Disable AMX-TF32 by default
AMX-TF32 feature support is disabled by default in binutils.
The AMX-TF32 instruction set extension is now disabled by default in binutils. This aligns with its depublishing and the lack of current or foreseeable hardware support. Test cases are updated to use an .arch directive for .amx_tf32 to maintain test integrity.
In Details
AMX-TF32, an advanced matrix extension feature, has been removed from the default enablement in binutils. This change reflects its depublishing by Intel and the absence of hardware support. The opt-in mechanism via assembler directives remains for backward compatibility and testing.
