Add the `__ARM_FEATURE_SME_MOP4` feature test macro, and a test checking
that it is correctly defined. The `+sme-mop4` flag itself was added
earlier, but the feature test macro and documentation weren't added.
gcc/ChangeLog:
* doc/invoke.texi: Document new extension flags.
* config/aarch64/aarch64.h (TARGET_SME_MOP4): New target macro.
* config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Define
`__ARM_FEATURE_SME_MOP4` macros when the relevant extension is enabled.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/pragma_cpp_predefs_4.c: Test that
`__ARM_FEATURE_SME_F8F16`, `__ARM_FEATURE_SME_F8F32`
and `__ARM_FEATURE_SME_MOP4` macros are defined when the
relevant extension is enabled.
* lib/target-supports.exp: Add `sme-mop4` to `exts`.
