[PATCH] D48580: [AArch64] Support reserving x1-7 registers.

[James Y Knight via Phabricator via llvm-commits]

I'm generally opposed to supporting the -ffixed- -fcall-used- and -fcall-saved- options from GCC. I think they're almost never the correct answer to a problem someone has.

In particular, here, it does seem that a calling convention annotation on the functions would be a significantly better way of spelling this.
