- other W^X systems
- some person trying to be funny with W^X on their system even if they dont have to

makes it so the shader cache goes properly in `XDG_CACHE_HOME`.
SOME people have it set to point to `/tmp` AND as a ramdisk, if they can do that they probably would want their shader caches to be there as well and wouldnt mind the extra hit from invalidations on reboot.
afterall, its a cache, not some holy data that needs to be kept at all costs.

Good fix or absolute trash?
For me it seems like an OK balance, better would be fully dynamic; but I believe 256 is a reasonable limit?

The GL shader profile hardcoded max_user_clip_distances to 8. Query the
device limit like the Vulkan path already does (it reads
maxClipDistances), so we use what the host actually reports.
Clamp to Maxwell's NumClipDistances (8) since the guest never produces
more than that and the SPIR-V output array is sized for at most 8. So a
host reporting fewer than 8 is respected, and one reporting more can't
overrun anything.

two main issues:
shader_environment.cpp
Support Mesa nv50_ir-compiled homebrew fragment shaders
Mesa nv50_ir (used by NZP-Switch via libdrm_nouveau) emits Maxwell SASS that differs from NVN in two ways our shader pipeline didn't account for, causing "infinite" loops during shader scanning.
How? TryFindSize() previously detected end-of-shader only via NVN's "BRA $-1" self-branch trailer (SELF_BRANCH_A/B). Mesa-compiled shaders end with an unconditional @PT EXIT and emit no trailer, so scanning ran past the shader and looped to MAXIMUM_SIZE.
Fix: Added a secondary match against @PT EXIT T (opcode 0xE30, predicate PT, flow T) as a fallback terminator. The mask is estrictive enough to reject predicated EXITs, conditional-flow EXITs, and sched control words, so well-formed NVN shaders see no ehavior change (their single @PT EXIT immediately precedes BRA $-1, and both detections return the same size).
load_store_attribute.cpp + attribute.h
IPA's is_perspective check only applied the ×position_w correction for IR::IsGeneric() attributes, and used a per-component SPH lookup. Two failure modes followed:
1. Mesa fragment shaders read varyings via legacy attribute slots
(ColorFrontDiffuse, FixedFncTexture, FogCoordinate) which are
remapped to generic varyings later by ConvertLegacyToGeneric. At
IPA-translation time they're still legacy, so IsGeneric() was
false and the inject was skipped — but the resulting GLSL/SPIR-V
varying was Smooth (perspective-correct), and the SASS still
issued its manual perspective dance via MUFU.RCP(ATTR_W)+FMUL,
compounding an extra ×clip_w factor. NZP fog (eye_z distance
varying) ended up as eye_z⁴×density² instead of eye_z²×density²,
saturating fog to white everywhere.
2. Even for legacy attrs that should inject, Mesa stores them in two formats selected by the IPA's interpolation_mode field:
Pass/Multiply/Constant → attr/w (perspective); inject ×position_w
Sc (ScreenLinear) → raw attr; do NOT inject
Unconditionally injecting for Sc dims vertex colors by 1/clip_w because there's no SASS multiplier to round-trip it back.
Fix: extend the IPA correction path to also fire on IsLegacyAttribute(), gated on interpolation_mode != Sc. While here, the generic-path check is widened from per-component to vector-level (first non-Unused PixelImap, with all-Unused fallthrough treated as Perspective) so it matches the GLSL interpolation qualifier picked by CollectInterpolationInfo — this fixes the same all-zeroed-imap case Mesa exposes for explicit generics. IsLegacyAttribute moved from translate_program.cpp's anonymous namespace into attribute.h next to IsGeneric so IPA can reach it.
Tested on NaziZombies:Portable (Switch homebrew): fog now matches real
hardware, vertex-colored geometry (hand, gun, decals) renders correctly.

So CreateInstance was enumerating instance extensions twice, and that could race if the driver returned a different list the second time. On some AMD iGPU drivers, we could enable an extension from the first list, then fail the second check with VK_ERROR_EXTENSION_NOT_PRESENT.
Fix this by enumerating once and passing that same snapshot into RequiredExtensions.

Homebrew (.NRO) program args support
Adds a 'program_args' setting and delivers it to NRO homebrews via libnx's homebrew ABI. NROs previously had no way to receive CLI flags (e.g. NZ:P's -noglsl).
Setting: program_args, Category::System, startup-only.
Surfaced in Qt + Android Debug sections.
NRO loader: builds a 4-entry 'ConfigEntry' table + argv at the data segment tail; prepends 'homebrew ' so user args land at argv[1]; scans for 'svc #7' to use as LR. Drops the stale NSO-style argdata append.
KProcess: stores loader-provided guest addresses; 'Run' switches to the homebrew entry (x0=config_ptr, x1=-1, lr=svc7) and patches the real MainThreadHandle into the ConfigEntry slot. Legacy NSO path unchanged.
Tested on NZP — args reach 'argv' correctly.
