Fix ArtDisassemblerTest.LoadLiteralVisit to read initialized values

ArtDisassemblerTest.LoadLiteralVisit tests the disassembly output of
ldr by reading from pc + 0. It was using 64-bit gpr and fpr registers
but we only know the contents of 32-bits (the encoding of the
instruction). The other 32-bits could be uninitialized or maybe even
unaccessible. So use 32-bit registers so we can expect a known value
always.
