In order to compile eager inner functions on a background thread we need to
keep the handles created during parsing and scope analysis alive until the
background compilation is complete. In order to do that, we allocate the
handles in a deferred handle scope and keep the deferred handles alive with
a shared_ptr in the ParseInfo and CompileInfo respectively.

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.

Add a simple benchmark for a TypedArray constructor. Run once with the
default pipeline and once with turbofan so that we can compare the
performance.

Also fixes a typo in the Regex for the result of the CopyWithin
benchmark which stopped the results showing up in the perf
dashboard.

in the spec is more complicated, but roughly speaking, it's when the
property is unconfigurable).

Collect code coverage from the available invocation counts.
The granularity is at function level, and invocation counts may
be lost to GC.

Coverage::Collect returns a std::vector of Coverage::ScriptData.
Each ScriptData contains a script ID and a std::vector of
Coverage::RangeEntry.
Each RangeEntry consists of a end position and the invocation
count. The start position is implicit from the end position of
the previous RangeEntry, or 0 if it's the first RangeEntry.
