With the software renderer, which now stores depth as the GE does, a
16-bit read or write at VRAM's 0x04200000 or 0x04600000 mirror goes to
where the GE's 16-bit or 32-bit color layout puts that depth pixel
(ppsspp-re geprobe exp88: the mirrors are the layout's exact inverse).
Games access depth there with nothing else, so other widths stay plain.
The accessors check the address, then whether the GPU core is the
software renderer (CoreParameter); the hardware renderers keep depth plain
and handle the layout their own way. The renderer keeps the layouts up to
date with the EDRAM address translation. With it, the JITs send 16-bit
loads and stores to the interpreter, and the IR passes don't change a
load's width to or from 16 bits.
The pspautotests that read depth through the mirrors now do so 16 bits
at a time, re-recorded on hardware unchanged.

A new FSinCos op writes both from one argument reduction. arm64 and x64 get
both back from a single call, packed in one double; RISC-V and LoongArch make
the two calls.

vh2f always went to the interpreter in the IR. A new FHalfToFloat op
converts the lower or upper half of a word, and the native backends
call vfpu_h2f for it like FSin. The legacy arm64 JIT now makes the same
call instead of computing the conversion inline; vh2f is rare, and the
call is much less code.

Vec4ClampToZero and Vec2ClampToZero only ever fed Vec4Pack31To8 and
Vec2Pack31To16, for vi2uc and vi2us. The packs now clamp negative lanes
to zero themselves, which saves an op and a vector temp, and lets x64
clamp with PACKUSWB's saturation after an arithmetic shift.
While at it, RISC-V compiles Vec2Unpack16To31, Vec2Pack31To16 and
Vec4Pack32To8, and LoongArch Vec2Unpack16To31, Vec2Pack31To16 and the
non-LSX Vec4Pack32To8, all of which went to the IR interpreter.
LoongArch's Vec2Pack32To16 and Vec2Unpack16To32 now take their scalar
path with LSX too, instead of falling back.

These were always interpreted. They're now IR ops that the native
backends compile to calls to vfpu_exp2 and vfpu_log2, like FSin and
FAsin. vrexp2 is FNeg followed by FExp2, which is how vfpu_rexp2
computes it.

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.
