    tree-inline: Remove .ASAN_MARK calls when inlining functions into
no_sanitize callers [PR114956]

    In r9-5742 we've started allowing to inline always_inline functions into
    functions which have disabled e.g. address sanitization even when the
    always_inline function is implicitly from command line options sanitize=
d.

    This mostly works fine because most of the asan instrumentation is done
only
    late after ipa, but as the following testcase the .ASAN_MARK ifn calls
    gimplifier adds can result in ICEs.

    Fixed by dropping those during inlining, similarly to how we drop
    .TSAN_FUNC_EXIT calls.

            PR sanitizer/114956
            * tree-inline.c: Include asan.h.
            (copy_bb): Remove also .ASAN_MARK calls if id->dst_fn has
asan/hwasan
            sanitization disabled.

            * gcc.dg/asan/pr114956.c: New test.
