Two cleanups to surrounding code preceed the actual implementation.

I did not find the ARM FPToFixedJS pseudo-function particularly helpful,
so I mostly cribed off of the Alpha cvttq implementation.  But I think
it all makes sense -- convert, produce the mod 2^32 result with NaN
getting INT32_MAX, set ZF iff the conversion is exact.

I've tested the aa64 version vs FVP with RISU.  I need to adjust my
FVP configuration in order to test aa32.

Hi,

This series failed the docker-mingw@fedora build test. Please find the testing commands and

I've reviewed patch 1; I'll leave 2 and 3 til you post v2.
