Revert of Use simple/fast macro version of MinMax in JS (patchset #2 id:20001 of https://codereview.chromium.org/1390023003/ )

Reason for revert:
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).

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.

Calling LowerInlineAllocationLimit from the bottom of Heap::Scavenge seems to be
a no-op.

  new_space_.LowerInlineAllocationLimit(
      new_space_.inline_allocation_limit_step());

LowerInlineAllocatoinLimit does the following things:

1. Set the inline_allocation_limit_step_ to the passed in value. No-op.
2. Calls UpdateInlineAllocationLimit(0). This is unnecessary here as it has
   already been called when new_space_.ResetAllocationInfo was called above.
3. Sets top_on_previous_step_. This again is unnecessary as it gets reached by
   ResetAllocationInfo as well.

Previously, arrow function scopes had a separate ScopeType. However,
Scope::DeserializeScopeChain() erroneously deserialized ARROW_SCOPE
ScopeInfos as FUNCTION_SCOPE. This could lead to bugs such as the
attached one, where "super" was disallowed where it should have
been allowed.

This patch utilizes the Scope's FunctionKind to distinguish arrow
functions from others. Besides fixing the above bug, this also
simplifies code in various places that had to deal with two different
ScopeTypes both of which meant "function".

This makes it explicit when the --ignition-filter pattern should be
applied to the script name instead of the function name by using a
proper "s:{name}" pattern. It also hardcodes it to be a prefix match
instead of an exact match, because that is all we need for test262.

This separates the core machinery and the heuristics involved with
