Daniel Sanders 4cf61e5269 [mips] Range check uimm20 and fixed a bug this revealed.
Summary:
The bug was that dextu's operand 3 would print 0-31 instead of 32-63 when
printing assembly. This came up when replacing
MipsInstPrinter::printUnsignedImm() with a version that could handle arbitrary
bit widths.

MipsAsmPrinter::printUnsignedImm*() don't seem to be used so they have been
removed.

# The 20-bit immediate supported by the standard encodings cause us to emit
# the diagnostic for the 20-bit form. This isn't exactly wrong but it is
# misleading. Ideally, we'd emit every way to achieve a valid match instead
# of picking only one.
