Lower the stack usage of a few functions
...
In vm/compaction.cpp I rescoped some variables to lower the stack usage
from 592 to 560 bytes. I wasn't very successful with this. The stack
usage is larger than it looks because methods on the structures used
take an implicit this pointer and a reference to the data (so the data
has to live out it's full scope and can't be put in a register).
In vm/debug.cpp I made a large (1024 bytes) stack allocated buffer
simply dynamically allocated.
In vm/os-unix.cpp I rescoped signal handling structures to not coincide
with each other and reduced a very large (1024 bytes) amount of stack
usage to less than 500 bytes.

VM: Fixup cast formatting after clang-format
...
clang-format doesn't recognize casts to non-pointer/non-template types
so it winds up adding a space between the right paren and the expression
and then failing to recognize prefix operators in the process
(e.g. foo = (cell) & bar; should be foo = (cell)&bar;). This commit
manually fixes up the major cases (fixnum, cell, all types ending in _t).

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.
