VM: storing some sample data in the heap ( #337 )
...
This is the first half of it. In the second half the samples array
should also be stored in the heap.

VM: rename of JIT_PUSH_IMMEDIATE to JIT_PUSH_LITERAL

The code template pushes both immediates and references so the name was
wrong.

VM: removes the OBJ-ERROR special object in favor of a constant
...
The special object contained the string "kernel-error" which were used
to tag VM errors. But it is simplier and removes a little complexity to
just tag them with a fixnum constant.

VM: more fine-grained control over which special objects to save

It removes a few roots that doesn't need to be saved in the image and
can save a few hundred bytes.

VM: put the singletons t, -1, 0 and 1 in the special objects table
...
Having them there instead of as fields in the vm struct removes a bunch
of special handling. This commit just adds them and doesn't remove the
old ones to avoid potential chicken-and-egg bootstrap problems.

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).

We also need to save C ABI volatile registers before calling the signal handler in order to be able to reliably resume. Add signal-handler and leaf-signal-handler subprimitives to preserve volatile registers before invoking the signal handler C function.
