llvm/lib/Target/AArch64/AArch64InstrFormats.td
Tom Coxon 01649dea92 [AArch64] Allow access to all system registers with MRS/MSR instructions. 
The A64 instruction set includes a generic register syntax for accessing
implementation-defined system registers. The syntax for these registers is:
    S<op0>_<op1>_<CRn>_<CRm>_<op2>

The encoding space permitted for implementation-defined system registers
is:
    op0 op1  CRn   CRm   op2
    11  xxx  1x11  xxxx  xxx

The full encoding space can now be accessed:
    op0 op1  CRn   CRm   op2
    xx  xxx  xxxx  xxxx  xxx

This is useful to anyone needing to write assembly code supporting new
system registers before the assembler has learned the official names for
them.
