This is a follow up to D48580 and D48581 which allows reserving arbitrary general purpose registers with the exception of registers with special purpose (X8, X16-X18, X29, X30) and registers used by LLVM (X0, X19). This change also generalizes some of the existing logic to rely entirely on values generated from tablegen. Differential Revision: https://reviews.llvm.org/D56305 llvm-svn: 353957
