This patch set is a further step to remove those intrinsics implemented
by inline assembly.
The touched intrinsics including those for fixed-point coversion,
frsqrt*, fabd and faddp.
The implementation approach is quite simple, for these intrinsics that
were implemented by inline assembly:
* If there are rtl instruction patterns introduced later, then migrate
to builtins which are backed by these patterns.
* If there aren't rtl instruction patterns, then add missing patterns,
and migrate to builtins.
AArch64 boostrap OK, no regression on linux configuration, also no
regression on big-endian bare-metal tests.
