The workflow and BUILD.md said ASAN_OPTIONS must end with ':' because tests append their own options with string_append. That is wrong: add_asan_test_options appends ':<options>', so ASAN_OPTIONS=detect_leaks=0 already gives detect_leaks=0:detect_stack_use_after_return=0 for the fiber test. Use detect_leaks=0 and remove the claim.
Document in BUILD.md, next to -DANYPS5_ENABLE_ASAN, what the Sanitizers workflow builds and runs, where the known failures are listed and what the job summary reports, and how to repeat a run locally: end ASAN_OPTIONS with ':' because tests append their own options, and set UBSAN_OPTIONS=print_stacktrace=1:halt_on_error=1 so undefined behavior fails the test.
The I/J reads take the BaryCoordSmooth input, but gl_FragCoord was declared
only for the offset kinds, so its w was read as the constant 0 and the
fragment function never read [[position]]; Apple GPUs then return the
weights unnormalized. Declare it with the built-in, and select on
gl_FragCoord.w > 0, which a compiler cannot fold as it can
min(b, b + |w|).
MoltenVK exposes VK_KHR_fragment_shader_barycentric but its MSL step
rejects PerVertexKHR, so the extension is disabled there and a pixel
shader whose I/J VGPRs outlive their v_interp_p1/p2 pairs takes the
generated barycentric stages, which accept only triangle lists without
primitive restart on a device without geometry shaders.
A new target flag, fragmentBarycentricBuiltins, enables the extension
for its built-ins only. The host interpolation check then keeps the
leftover I/J reads (all perspective or all linear, at the fragment's
default position) and reads them from BaryCoordKHR or
BaryCoordNoPerspKHR, while the interpolated attributes stay hardware
varyings. Raw vertex parameters and I/J at an offset or a sample
position still take the generated stages. Apple GPUs return
unnormalized perspective weights unless the fragment function reads
[[position]], so each perspective read keeps a neutral use of
gl_FragCoord.w, loaded as a float. Devices with the full extension are
unaffected; the request serialization moves to version 45.

asinh_nid_postfix called the host libm's asinh. It now follows the branches and
thresholds of FreeBSD msun's s_asinh.c (release/11.4.0): below 2^-28 it returns x,
up to |x| = 2 it uses log1p, up to 2^28 log(2|x| + 1/(sqrt(x*x+1)+|x|)) and above
that log(|x|) + ln2. Up to |x| = 2 the results are bit-identical to msun; above 2
they depend on the host log this file still uses.

Keep #9694's coverage check for targets without CMASK or DCC keys and skip it only for a fast-clear eliminate over a CMASK target without DCC keys.
