Previously, name conflicts between var and let declarations were only
made into exceptions if they were visible at parse-time. This patch adds
runtime checks so that sloppy-mode direct eval can't introduce conflicting
var declarations. The change is implemented by traversing the scope chain
when a direct eval introduces a var declaration to look for conflicting
let declarations, up to the function boundary.

Scope has no subclasses, so "protected" should just be "private". And
there is no ParserFactory class, so making it a friend doesn't buy us
anything.

Make the end position of a regexp literal the first character following the regexp. This matches the behaviour of number literals and string literals, as well as single-character tokens.
This change corrects the lazy-parsing of arrow functions with concise bodies, whose last token is a regular expression literal.

This contains bugs, as found by mstarzinger. Reverting until we can find a clean fix (maybe it should be an inline function instead of a macro).

Without that, it has a few false positives about out-of-bounds array accesses.
Also makes the clang static-analyzer happy.

This adds support to also lower stores to global property cells in state
kConstant or kConstantType, where we need to deoptimize eagerly in case
we have a value/type mismatch.
Also fixes bugs in the construction of the frame states in the

This fixes several warnings when cross-building using GCC (since r31087,
5cf1c0b).
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.
