This fixes several warnings when cross-building using GCC (since r31087,
5cf1c0bc).

In particular, CPURegister::code() now returns 'int', matching the other
platforms (and the coding style guide). The rest of the patch consists
of similar changes to make this work.

This change removes the unswept free bytes counter.

The new approach
- directly decrements allocated memory and capacity before sweeping (using live
  bytes from the marker), and
- adds back capacity during refilling a free list.

This is another pre-work for moving around free lists while keeping the counters
in a sane state.

The previous approach allowed us to nail down how much memory is to-be-swept.
However, there were no users of this as we only used it do decrement it from
allocated memory (which still accounted for dead objects).  If we want to keep
track of unswept free bytes in a space during compaction we can introduce a
separate new concurrent counter for this purpose.

There's no need for a dedicated ToBoolean builtin in JavaScript, since
ToBoolean(x) can easily be expressed in JavaScript as !!x, which has the
additional advantage that the compilers are able to properly optimize
that (out of the box).

For property cells with cell type kConstantType, we can compute an
appropriate JavaScript type based on the current value of that cell.
Numbers cannot use Type::Of here, because the type might be too precise,
so we handle smi and heap number specially.
