[26/32] Remove global call sets: regrename.c

This patch makes regrename use a similar mask-and-clobber-set pair to IRA when tracking whether registers are clobbered by calls in a region. Testing for a nonzero ABI mask is equivalent to testing for a register that crosses a call. Since AArch64 and c6x use regrename.h, they need to be updated
