Don't throw an error in 'info registers' for unavailable MIPS registers.
'info registers' for MIPS throws an error and when it first encounters
an unavailable register. This does not match other architectures
which annotate unavailable registers and continue to print out the
values of subsequent registers. Replace the error by displaying an
aligned "<unavailable>". This string is truncated to "<unavl>" when
displaying a 32-bit register.
