Joe Groff 7c9332e966 cpu.x86.*: clean up signal handler prolog code
Also bump the signal handler frame sizes up again since it looks like we shrank them too much.

Joe Groff 9236c05e60 vm: stage code block map fixup properly for GC
Don't update the map until the very last thing, and pass untranslated addresses to the iterator functors. Somewhat complicated by the fact that, for startup_fixup, the map is initialized with fixed-up values, so the fixup functor needs a flag indicating whether it operates with a fixed or unfixed code heap map.

Joe Groff ef38688e87 vm: method to calculate frame size for address
If we're before the prolog or or in a leaf procedure, the stack frame is really a leaf frame created by the signal handler, with a known fixed size, instead of the real stack frame (if any) with a different size.

Joe Groff 083b856604 vm: reinitialize all_blocks from scratch after gc

Joe Groff 4bbb2f5b72 vm: only verify all_blocks set if it's invalid
Verifying on every sample is way too slow to be practical when debugging bootstrap.

Joe Groff 0a1a252cdb vm: replace assert with FACTOR_ASSERT
Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

Joe Groff 2705fc67cb vm: keep a set of all code_blocks in the code_heap
This way looking up code blocks by return address is an O(log n) set lookup rather than an O(n) linear scan.

This prevents an endless loop caused by the nvidia drivers on linux.
