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.

vm: strip out call-counting profiler
...
This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318 .

vm: Revert extra canary page before callstack
...
This reverts commit 7d5c8d6990385b94569116a23163d7e75ae21f49. We pretty much can't avoid unwinding frames without some more drastic redesign.

vm: allocate an extra canary page before callstack
...
This will let us safely unguard the callstack overflow guard page as a grace page so the callstack overflow handler can do its business without discarding frames.

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

Big cleanup of literal table and relocation-related code
...
- new way to iterate over instruction_operands cleans up relocation code
- move some methods out of the VM class to clean up code
- if debugging is on, die earlier if attempting to allocate inside GC
- callback heap entries are now code_blocks
- replace block_granularity with data_alignment
