Made the FileCheck variable names more generic, to limit diffs between test updates.  Names are now based on register class with a uniquifying count that tracks redefinitions of registers so that changes in register def-use changes can be seen.

The X86 regexps for GPRs are complicated because only parts of register names are common across all super-/sub-classes and the prefix and suffix (non-common) parts of the names varies based on the "base" GPR name.
