Unfortunately StringAdd is not pure in V8 because we might throw an
exception if the resulting string length is outside the valid bounds, so
there's no point in having a simplified StringAdd operator.

Along the way:
- Thread isolate parameter explicitly through code that used to
rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
affected code
- Change Hydrogen New<> instruction templates to automatically
pass isolate

Allow reservation of additional input capacity when creating nodes to prevent switching to deque representation when adding well-known additional inputs.
Also ensure that only a single temporary buffer is used to create temporary input arrays before allocating nodes.

The StaticParameterTraits are broken by design, and cause way too much
trouble. The compilers usually pick the wrong specialization (i.e. the
default specialization is picked for Load and Phi even tho there is a
specialization for MachineType), which is not only the reason why GVN is
ineffective and slow, but can also lead to correctness issues in some
rare cases.
Also clean up some minor bugs/inconsistencies on the way.
