Resolves the shader debt file bullet by bullet: main's EmitSetAttribute entry, and this branch's PERSP_SAMPLE/LINEAR_SAMPLE and pixel-position entries.
fopen resolved the random device paths to a host file that does not
exist and failed with ENOENT, while open and sceKernelOpen already serve
them from host entropy. A read-only fopen of either path now returns a
stream whose fread fills the buffer with host entropy. setvbuf, feof,
ferror, clearerr, the stream locks and fclose work on it, fflush returns
0 as on a FreeBSD stream that is not writing, other stream functions
throw, and opening the paths for writing throws as in libkernel.
ProsperoTV (PPSA99003) reads its phone pairing code this way and showed
"Code expired or unavailable".

The initial import of a native multisampled depth target only proceeds
when every HTILE word proves the same clear value, so no compressed Z
planes are read from guest memory. ITERATE_256 only changes how the DB
and the texture unit walk compressed MSAA Z planes (Mesa
ac_descriptors.c: "TC-compatible MSAA HTILE requires ITERATE_256").
The HTILE footprint (Addrlib) and the HTILE clear words (Mesa
radv_get_htile_fast_clear_value) do not depend on it. The import no
longer requires it; the texture's ITERATE_256 must still match the
target's.
Unblocks PPSA27836 (Onimusha: Way of the Sword), which samples a
four-sample D32 target with pipe-aligned HTILE and ITERATE_256 off.

In PS4 executables and modules the bytes between unwind functions are
16-byte slots of function tails and padding, and a tail can begin inside
an instruction, such as a lone REX byte before a 15-byte NOP. The
syscall and call-site scans decode the executable segment linearly, so
such a slot failed the relink with "Cannot decode instruction".
For images with a PT_SCE_DYNLIBDATA segment the scans now receive the
unwind function ranges. Outside every range an undecodable byte is
skipped and decoding resumes at the next byte, and a decoding that would
cross into a range ends at its start, so gap bytes cannot change how a
function is decoded. Inside a range a decode failure still fails the
relink, and images without unwind ranges are scanned as before.

Resolves MultisampleTarget against #6635: the sampled view takes the requested view type and keeps the sampled-only usage when the target has a storage view for the guest's sample order.
In a payload process on a PS5 (firmware 12.70), I386_GET_FSBASE (7) and
I386_GET_GSBASE (9) wrote 4 bytes, the low 32 bits of the FS and GS
bases, and failed with EFAULT for a null argument; both threw here. On
Linux x86-64 hosts they now do the same.
The nine operation numbers tried that FreeBSD 11's amd64 sysarch has no
case for (2, 5, 6, 12, 127, 133, 134, 1000 and -1), each with a null
argument, failed with EINVAL there, as its default case does, and threw
here. Every such number now returns EINVAL on every host.
Threads made with pthread_create and scePthreadCreate started with their
creator's GS base there; the test now checks that a guest thread does so
on Linux. The sysarch debt entry records these measurements and what
AMD64_GET_XFPUSTATE and I386_GET_XFPUSTATE returned there; both still
throw here.
reachingWriter followed only fall-through and direct branches, so a V#
load on a path that reaches the loop through an s_setpc_b64 jump the
control flow analysis resolves was not seen, and another load could be
taken as the only writer. The walk now follows those jumps. It also
fails at s_call_b64 targets, whose callers it does not follow, instead
of walking from a function entry into the code above it.

The four guest_arena tests still pass with the mach_vm_region walk
disabled, because TryReserve marks every 1 GiB chunk it cannot reserve
as occupied. guest_arena_gap reads the host map before the arena
reserves its range and requires a fixed guest mapping in free space
that shares a chunk with a host region to be accepted.
The debt entry also records that on macOS 27.0.1 (M4 Pro) the
unmappable range starts at 0xF_C000_0000.
