Aarch64: Add FMA and FMAF intrinsic and corresponding tests
This patch introduces inline definitions for the __fma and __fmaf
functions in arm_acle.h for Aarch64 targets. These definitions rely on
__builtin_fma and __builtin_fmaf to ensure proper inlining and to meet
the ACLE requirements [1].
The patch has been tested locally using a crosstool-NG sysroot for
Aarch64, confirming that the generated code uses the expected fused
multiply-accumulate instructions (fmadd).

gcc/ChangeLog:
* config/aarch64/arm_acle.h (__fma, __fmaf): New functions.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/acle/acle_fma.c: New test.
