[asan] add a test for use-after-return and exceptions and fix it. Not 100% sure this is a complete fix, will keep looking for harder cases.

[asan] fully re-implement the FakeStack (use-after-return) to make it faster and async-signal-safe. The implementation is not yet complete (see FIXMEs) but the existing tests pass.

[asan] initialize fake_stack lazily and increase its maximal size. This makes -fsanitize=address,use-after-return more robust: all SPEC tests pass now. In the default mode thread stacks become a bit smaller.

[sanitizer] found a bug by code inspection: CHECK(a=b) instead of CHECK(a==b). Was puzzled why lint did not catch it. Turns out this check was disabled for asan source. fix all cases and enable the check

[ASan] Speed-up initialization-order checking: create and use fast versions of PoisonShadow functions, store copies of __asan_global descriptors in a vector instead of list of pointers. This gives 3x speedup on both benchmarks and real binaries with lots of globals.
