DT_SCE_STRTAB, DT_SCE_SYMTAB, DT_SCE_RELA and DT_SCE_JMPREL are offsets
into the PT_SCE_DYNLIBDATA segment, as the code analysis and the guest
image reader already read them, but the pipeline read them as file
offsets. That only works when the segment starts at file offset 0, as in
the test fixtures. A PS4 executable (CUSA00900) keeps the segment at
0x53e9b40, so the relinker read its relocations from the code and failed
with "Dynamic string offset is outside DT_STRSZ". Without the segment the
values are still read as file offsets.

Shaders with f64 instructions now declare DenormPreserve for 64-bit floats
when the device reports shaderDenormPreserveFloat64. Without it Mesa ANV
flushed the subnormal result of v_fma_f64 to zero.

Port FreeBSD 11 lib/libc/stdlib/random.c (freebsd-src 4ab2e064): the
additive feedback generator with the default 128-byte TYPE_3 table,
good_rand seeding, state sizes rounded down to 8, 32, 64, 128 or 256
bytes, setstate returning the previous state, and initstate returning
null below 8 bytes without setting errno. Calls are serialised by one
lock; a null state throws.
The import audit of the homebrew catalog on main 262c0316 lists them as

A plain image_sample that says DIM 2D on a 1D T# takes its texel and its LOD
from the first coordinate alone, measured on RDNA2 (gfx1036) with the
hardware oracle. Astro's Playroom draws with such a pair.
DB_ALPHA_TO_MASK 0xaa01, the enable bit with the four offsets at 2 and no OFFSET_ROUND, reaches the pixel stage, which keeps a pixel when its MRT0 alpha is at least one half. Dithered or rounded settings, and an MRT0 that is missing, swizzled, packed or exported without a floating-point alpha, still throw. God of War Sons of Sparta (PPSA28997) stopped on it a few minutes into play.
The AMM ranges were reserved address-less on first use, so they took the
lowest free address of the arena, directly after the title's last mapping,
where the title's next hinted maps go. They are now reserved at a fixed
place, the last 64 GiB of the guest arena, which maps without MAP_FIXED and
the hints derived from them do not reach; a reservation that cannot be made
there throws.
Fixes#3146
Measured on a PS5 (firmware 13.60):
- sceRudpInit rejects a null pool or a size of 0 or less with
INVALID_ARGUMENT, and a pool under 0xC58 bytes or not 8-byte aligned
with MEMORY (0x80770007).
- sceRudpGetStatus rejects a null pointer or a byte count of 0 or above
0xF8 with INVALID_ARGUMENT and reports the live context count at 0x64.
