Henrik RydgårdandClaude Opus 5 315d128141 VFPU: make vmfvc see a pending prefix, and actually write its result

Comp_Vmfvc read vfpuCtrl[] straight from the context in all four
backends, while the mfvc path in Comp_Mftv flushes first, with the
comment "In case we have a saved prefix" - so "vpfxs X" followed by
"vmfvc sN, $128" returned the stale value in memory. The IR frontend
flushes only for the three prefix registers, which is the tighter form,
so vmfvc does the same there.

On ARM and ARM64 the fix alone wouldn't have been observable: those two
map the destination with no flags, leaving isDirty false, so the flush
dropped the loaded value without storing it. x86 already passes
MAP_DIRTY | MAP_NOINIT. That part is a fix of its own, but the two are
inseparable in this function - a vmfvc that reads the right value and
then throws it away is no better.

ArmAsm.cpp

Add a utility function for all the ABIs to call functions with a pointer arg. Use to call Advance from the JIT with the MIPSContext. Indent some code better.
