Flyinghead b99b3450c8 sh4: compute fsrra as 1/sqrt(x) instead of sqrt(1/x)
Fixes invisible chaos emerald in Sonic Adventure cutscene after Emerald
Coast.
Partial revert of ec3ad9b.
Issue #1600

Flyinghead ec3ad9b328 sh4: use double for fipr and ftrv. divide before sqrt for fsrra. ssa fix
dynarec: use double to implement fipr and ftrv except on arm32
interpreter: always use double for fipr and ftrv
fsrra: perform division before square root
fmac: use std::fma or native fma op
get rid of unused dynarec op shop_swap
ssa: dead register pass must assume interpreter fallback modifies all
registers
ssa: replace reg+0 address by reg in constant propagation pass
decoder: replace address offset 0 by null param for indexed mem access

Flyinghead 879372cb79 rec-x64: use FMA when available
x64 vfmadd is a better implementation of the sh4 FMAC op, so use it if
available. Fall back to mul+add if GGPO is enabled to avoid desyncs
between different cpu models.

Flyinghead 62085539a7 dynarec: reg alloc 64-bit regs. avoid some interpreter fallbacks
Option to reg alloc 64-bit regs in two host regs. Used when FPSCR.SZ ==
1 (64-bit reg and memory transfers.) Enabled for arm, arm64 and x64
(windows only) dynarecs.
Don't fallback to interpreter when FPSCR.PR==1 (double precision) for
FMOV, FLDS and FLTS.
