Make ARM RegNames[] static like X86 (no ARM syms in X86-only build).

The X86 code was switch out here:
https://codereview.chromium.org/1216933015/diff/150001/src/IceTargetLoweringX86Base.h

The important bit might be that it's static const char * instead of
static IceString. This removes static ctor/dtor for that array,
which LTO doesn't seem to be able to optimize out, leaving ARM
and MIPS symbols in the X86-only build. After changing it to static
const char *, LTO is able to optimize out the ARM and MIPS
symbols in the x86-only build, saving about 3KB of .text and
few bytes of .rodata.
