VM: change type of bignum_roots and remove unnecessary not-null checks
...
Declaring bignum_roots to contain bignum** instead of cell avoids some
superfluous casts. Casting it to cell is wrong because the items in it
are never tagged. And due to a earlier commit, bignum_roots will never
contain NULL:s so checking for them is not needed.

VM: rename all variables named "bignum" in bignum.cpp to "bn"
...
The name can cause compiler errors because it's the same as the type
name. It only matters in some functions, but I like consistency so I
renamed it everywhere.

VM: refactoring that removes data_root_ranges

instead of storing data_root_ranges in data_roots, you can just store
cell pointers directly. the advantage with doing it that way is that
registration and traversal code becomes simpler (and slightly faster).

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: more defense against multi-faulting
...
* Clear faulting_p from a safepoint rather than inside general_error, because jumping into unwind-native-frames could blow up.
* Handle multiple faults from fatal_error by breakpointing. Is there anything else we can safely do at that point?
* Verify memory protection faults in the top half of the signal handlers because signal dispatch could fault. Treat memory faults during gc or fep as fatal errors.
* Add a function factor_vm::abort() that restores the default SIGABRT handler and ::abort()s. Use it from fatal_error() so we get useful context from gdb and so the user gets feedback from the system crash reporter that Factor blew up and didn't just disappear.
* In factorbug(), don't proceed with .s .r .c if it would be unsafe to do so.
* Don't pile on signals if we've already called fatal_error().

...
It's not robust currently to raise an exception because a lot of our code that isn't already written with exceptions in mind breaks. Also, a signal is likely to be received by an FFI callback installed on the IO multiplexer, which will cause Factor to die since the callback cannot handle the exception. We need a more robust solution to dealing with SIGINT.
Also lay some groundwork for counting profile samples and reporting non-interrupting asynchronous signals.

Change how non-volatile register preservation is done in alien callbacks, with the aim of fixing callbacks on PowerPC, and to eventually eliminate assembly code from VM
...
- Simplify calculation of offset in relocation table
- Open-code %alien-callback
- Remove magic_frame hack from context objects
- Move magical return instruction from optimizing compiler backend into callback entry stub

- callback heap entries are now code_blocks
- replace block_granularity with data_alignment
