So, this one fails because we don't instrument string literals, in GCC
they aren't anything close to global variables (like they are in LLVM?)
Perhaps we could, handle STRING_CSTs in categorize_decl_for_section
like flag_mudflap handles them (essentially disable -fmerge-constants),
add code to output_constant_def_contents to emit the padding around it
if protected and in asan_finish_file traverse constant_pool_htab (),
looking for STRING_CSTs that were TREE_ASM_WRITTEN.

This one fails to match because the filename in that case isn't
asan_test.cc, but asan_test.C. Can it use say
ASAN_TEST_NAME macro,
#ifndef ASAN_TEST_NAME
# define ASAN_TEST_NAME "asan_test.cc"
#endif
and replace "zoo.*asan_test.cc" with "zoo.*" ASAN_TEST_NAME (and similarly
in one of the disabled tests)? Then asan_test.C could just
#define ASAN_TEST_NAME "asan_test.C"
before #include "asan_test.cc"
