[libc] Don't rely on LIBC_HAS_SANITIZER when enabling null checks. (#150341)

2025-07-24T21:15:46+00:00

LIBC_HAS_SANITIZER (which is defined if ASan, MSan, or UBSan is enabled)
is currently used to implicitly disable null checks, normally enabled
via LIBC_ADD_NULL_CHECKS config value. Remove this condition, and rely
purely on the config value instead:

* LIBC_HAS_SANITIZER will be true even for UBSan modes which doesn't
rely on null checks at all (e.g. -fsanitize=alignment)
* null checks today (implemented via __builtin_trap) should function
normally today even when sanitizer is enabled - trap is still a trap
* tests have been migrated to WITH_SIGNAL(-1) which doesn't prescript a
particular signal / exit-code, and thus should pass even if sanitizers
override the default ones.

[libc] Expand usage of libc null checks. (#116262)

Fixes #111546

This reverts commit 1e6e845d49a336e9da7ca6c576ec45c0b419b5f6 because it
changed the 1st parameter of adjust() to be unsigned, but libc itself
calls adjust() with a negative argument in align_backward() in
op_generic.h.
