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.

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.

Tease out symbol name and library in undefined_symbol() handler, for friendlier errors when calling an unresolved C function name. Fixes #93

compiler: new "binary literal area" at the end of a word's machine code stores constant floats and SIMD vectors; this allows ##load-reference/##load-memory fusion to be performed on x86-64, with a RIP-relative address reaching the data; also simplifies VM since custom relocation types used by the previous 32-bit-only optimization are no longer needed

vm: modify-code-heap primitive now takes a pair of parameters, update-existing? and reset-pics?. If no generic words were changed, PICs do not need to be reset. If no existing words were redefined, the code heap doesn't have to be traced at all. Speeds up compilation of PEGs since those create lots of compilation units
