compiler.tree.propagation.*: implements downgrading to fixnum for the
...
mod word, maybe a first step in solving #224
factor_vm::primitive_bignum_mod is changed so that it outputs a fixnum
if the value is small enough. Then the compiler can take advantage of
knowing that expressions like [ >bignum 10 mod ] always result in a
fixnum [-9,9] and inline more arithmetic.

platform.hpp: Indent so I can see wtf is going on with the preprocessor control flow.
...
Look for ``__linux__`` on linux instead of ``linux`` because compiling with
-std=c++11 removes the ``linux`` preprocessor symbol.

VM: move free_list_allocator<Block>::next_allocated_block_after to

VM: new functions raw_fclose and raw_fread

These need to be used when the image is loaded because there is no
context so you can't throw io errors yet.

VM: possible fix for #1319 .
...
Fix for reset_context() so that the top two stack items are never
removed from the stack so if the parent->init_context(ctx) call triggers
a GC, those items are never collected.

016614747d
VM: the delete_context() and reset_context() api functions can be
...
simplified a bit
The functions always operates on parent->ctx, so passing a context*
parameter is redundant. This enables shorter assembly code for
the (start-context-and-delete) and (set-context-and-delete) primitives.

Reorganising bootstrap files
...
All the bootstrap.factor scripts in cpu/ are run by the bootstrap to
make boot images, but aren't used otherwise. So I think it's cleaner to
put them in one directory inside the bootstrap hierarchy.

VM: the compiler doesn't emit any live overinitialized locations anymore
...
Any overinitialized location immediately becomes garbage and is not
reused again. This is very nice because then the gc maps can be
simpler again.
