On a host subgroup narrower than 32 lanes, threadBit reads an EXEC
written with s_mov_b32 or s_mov_b64 at bit LaneId & 31 of EXEC_LO, and
LaneId is the subgroup invocation id. Every lane at or above the host
subgroup size therefore reads the bit of a lower lane, in wave32 and
wave64 alike. An EXEC produced by a compare stays consistent because
its ballot is subgroup-local as well. Found while investigating the
llvmpipe failure of #751.
Returns the CPU mask threads get by default (DEFAULT_THREAD_AFFINITY,
0x1FFF), the value itself rather than an error code.

PPSA21564 and PPSA21567 import std::_Fiopen (NID vYWK2Pz8vGE), the only libc
NID the host libc lacks. Without it the executable fails to load against
the host libc when the title's own libc.prx is left out of the guest
conversion, which is how the Linux runs of PPSA21564 avoid the libc.prx
binding crash. The values of the open mode and the meaning of the
protection argument are unknown, so the export throws when called; it was
never called in a 300 s run of PPSA21567.

No additional content is installed, so sceAppContentAddcontMount returns
SCE_APP_CONTENT_ERROR_NOT_FOUND with the mount point untouched, and
sceAppContentAddcontUnmount finds no mount to release. A missing label
or mount point is a parameter error. The library gets its own
CMakeLists for the new guest_appcontent test.

Registration of owners and resources fails with
RESOURCE_REGISTRATION_UNAVAILABLE, so no handle is ever valid: the owner
and resource getters, sceAgcDriverSetResourceUserData,
sceAgcDriverRegisterGdsResource, sceAgcDriverFindResourcesPublic,
sceAgcDriverUnregisterAllResourcesForOwner and
sceAgcDriverGetDefaultOwner return the same error.
sceAgcDriverUnregisterWorkloadStream mirrors the accepting
RegisterWorkloadStream. No capture, trace or submit validation ever runs,
so their status queries report false.

sceVoiceQoSInit accepted only app type 0x20000000 and threw for every
other value. PPSA26344 v1.008 passes 0x10000000 at both of its call
sites, so its initialization threw.
Accept 0x10000000 as a second known app type. Its meaning is unknown,
so the constant is named after the value, and it is handled like
0x20000000; the block stays unused. A null or empty block, a second
initialization and every other app type still throw.
guest_voice_qos_tests now takes the app type as its argument and runs
in ctest once per accepted value, because sceVoiceQoSEnd still throws
and one process can initialize only once.
sceAudioOut2PortCreate threw for 12-channel ports, which PPSA26344
creates as its two 7.1.4 float beds (data format 0xc00).
Each accepted layout (1, 2, 6, 8 or 12 channels, float or int16) now
folds into the stereo mix through a coefficient table: centre, side,
back and top front channels at -3 dB, top back channels at -6 dB into
the front, LFE dropped. Zero coefficients are skipped, so NaN or Inf on
a dropped channel does not reach the mix. Ports of 3, 4, 5 or 7
channels, which were mixed as L/R, now throw, as do other counts and
formats with any of bits 12-31 set. The assumed format fields,
channel order and coefficients are listed in TechnicalDebt.
The new audio_out2_port_layouts test checks each layout's fold, float
and int16, and the formats that throw.
