Check that the symbol sets exported by the minimal runtime and the full
runtime match (making exceptions for special cases as needed).
This test uses some possibly non-standard nm options, and needs to
inspect the symbols in runtime dylibs. I haven't found a portable way to
do this, so it's limited to x86-64/Darwin for now.

This eliminates a few inconsistencies between the symbol sets exported
by RTUBSan and RTUBSan_minimal:
* Handlers for nonnull_return were missing from the minimal RT, and
are now added in.
* The minimal runtime exported recoverable handlers for
builtin_unreachable and missing_return. These are not supposed to
exist, and are now removed.

This reverts r313189, and adds a use of darwin_filter_host_archs() for
ubsan-minimal.

We're seeing strange issues on the public GreenDragon Darwin bots which
we don't understand. x86_64h tests are still being run on pre-Haswell
bots despite the added checks in test/ubsan_minimal/lit.common.cfg,
which were verified on our internal bots.
I'm unable to ssh into the affected public bot, so for now am trying a
more aggressive check which disables all x86_64h testing for
ubsan-minimal on Darwin.

Checking if config.target_arch is x86_64h doesn't work (the 'h' suffix
is dropped here, and I didn't account for that). Instead, check to see
if '-arch x86_64h' is in the cflags.
Tested on a pre-Haswell bot.

Should un-break this bot:

Summary:
An implementation of ubsan runtime library suitable for use in production.
Minimal attack surface.
* No stack traces.
* Definitely no C++ demangling.
* No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general.
* as simple as possible
Minimal CPU and RAM overhead.
* Source locations unnecessary in the presence of (split) debug info.
* Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at.
* above two items save 3% binary size.
When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.
