have right now. Both the patterns and target specific nodes can change as
we move forward with this work.

If the target says that an extending load is not legal, regardless of whether
...
it involves specific floating-point types, legalize should expand an
extending load to a non-extending load followed by a separate extend operation.
For example, we currently expand SEXTLOAD to EXTLOAD+SIGN_EXTEND_INREG (and
assert that EXTLOAD should always be supported). Now we can expand that to
LOAD+SIGN_EXTEND. This is needed to allow vector SIGN_EXTEND and ZERO_EXTEND
to be used for NEON.

CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead

of the current thread. This has the unfortunate effect that assert() and abort()
will end up bypassing our crash recovery attempts. We work around this for

assert handler and abort.
