VFPU: vsqrt, vrsq, vrcp and vnrcp are exact in every backend
...
These went through the host's sqrt and division everywhere except the
interpreter's vrcp and vnrcp (vsqrt and vrsq there only behind
USE_VFPU_SQRT, now gone). They now always give the PSP's bits: the IR
gets FVSqrt (FSqrt stays the FPU's IEEE sqrt.s), and FRSqrt and FRecip,
which only the VFPU emits, become vfpu_rsqrt and vfpu_rcp; the IR
interpreter and the x64, arm64, RISC-V and LoongArch backends call them.
The old JITs call them directly, the ARM ones keeping the lanes in
callee-saved registers across the calls. cpu/vfpu/exact now passes on every core.

This is required to make ExtractIR not a member of the various backends.

Skip flushing FPU/VFPU regs if none were allocated.
...
They're not used as often, so this usually saves time. About 1% during
tests.

Second attempt at flushing multiple VFPU regs using VSTMIA.
...
Also disabled, but seems to work, just needs testing.
Much better code this time and works for VFPU regs not just FPU regs.
