fp-int-convert-double.c ICEs on mipsisa64-elf when compiled
with "-O2 -mabi=o64 -mips16". This is a recent failure;
it appears to be a latent bug exposed by:

PR target/35083
* optabs.c (expand_float): Do not check for decimal modes when
expanding unsigned integer through signed conversion.
At first glance, it appears to be a reload inheritance bug.
I'll have a look later today.
