Issue 118040043: Support asan-fixed-shadow-offset in GCC
DescriptionThis patch adds support for non-fixed shadow in asan stack instrumentation.
It is required for Kernel AddressSanitizer, as the shadow offset is not known at the compile time, and the shadow may not be allocated during the early boot stages.
This option is intended to be triggered by -fsanitize=kernel-address option, together with enabling instrumentation with calls.
