Have the sanitizers trap rather than abort.

Browse source 
abort() seems friendlier, but in practice it puts a couple of irrelevant
libc.so frames on the top of the stack trace and clobbers all the
registers that might have helped remotely debug a sanitizer failure.
Let's switch to trapping directly in the sanitized code instead.
