62f929ff4c Use nullptr instead of NULL where possible
New code should use nullptr instead of NULL.

This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

1fc93f2e2d [Compiler] Enable use of seperate zones for parsing and compiling.
In order to allow parallel compilation of eager inner functions, we need to
seperate the zone used for parsing (which will be shared between all the
parallel compile jobs) and the zone used for compilation. This CL changes
CompilationInfo to require a zone (which can be different from the zone in
ParseInfo). We then seal the ParseInfo zone after parsing and analysis is done
to prevent any further allocation in that zone, so that it can be shared
(read-only) with the parallel compile jobs.

Moves ownership of the parsing Zone to ParseInfo with a shared_ptr. This is
in preperation for enabling background compilation jobs for inner functions
share the AST in the outer-function's parse zone memory (read-only), with the
and zone being released when all compilation jobs have completed.

ab5379074d [parser] Deprecate ParseInfo constructor taking closure.
This removes the {ParseInfo} constructor consuming a closure, replacing
all uses to pass only the shared function info. The goal is to make the
fact that parsing is independent of a concrete closure explicit.

f6bd23f244 [turbofan] Enforce native context specialization.
There were once plans to generate cross-context code with TurboFan,
however that doesn't fit into the model anymore, and so all of this
is essentially dead untested code (and thus most likely already broken
in subtle ways). With this mode still in place it would also be a lot
harder to make inlining based on SharedFunctionInfo work.

This enables the {BytecodeGraphBuilder} whenever heuristics in the

There no longer needs to be an explicit flag passed in order to build
