aarch64: Reintroduce FLAG_AUTO_FP
The flag now known as FLAG_QUIET is an odd-one-out in that it
removes side-effects rather than adding them. This patch inverts
it and gives it the old name FLAG_AUTO_FP. FLAG_QUIET now means
"no flags" instead.
gcc/
* config/aarch64/aarch64-builtins.cc (FLAG_QUIET): Redefine to 0,
replacing the old flag with...
(FLAG_AUTO_FP): ...this.
(FLAG_DEFAULT): Redefine to FLAG_AUTO_FP.
(aarch64_call_properties): Update accordingly.
