Moves the temporary register allocator out of the bytecode array
builder into TemporaryRegisterAllocator class and adds unittests.
Particular must be taken around the translation window boundary
motivating the addition of tests.
Also adds a Clear() method to IdentityMap() which is called by
the destructor. This allows classes to hold an IdentityMap if
they are zone allocated. Classes must call Clear() before the zone
is re-cycled or face v8 heap corruption.

This removes the requirement for handles as arguments, but also removes
concurrency support, which is not being used at the moment.
Supporting concurrency could be done by introducing a sibling class to
IdentityMap that includes RelocationLock on method calls.

This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we
allow explicitly.

This data structure uses the public heap API only and is not specific
to any heap internals. It should be usable throughout V8 and inclusion
of the header file should not be restricted.
