This allows us to reuse AstValueFactory's string table across multiple
parsers, while still releasing memory after each individual parse.
This is mild overkill for all the single parses that don't reuse
AstValueFactories, but there at least the AstRawStrings now end up
grouped together in memory, so that might have mild cache benefits.

Introduce a ReusableUnoptimizedCompileState class, passed to ParseInfo,
which stores a couple of pointers and most importantly the Zone and
AstValueFactory of the parse. This allows the Zone and AstValueFactory
to be reused across multiple parses, rather than re-initialising
per-Parse.
With this, we can amend the LazyCompileDispatcher to initialise one
LocalIsolate, Zone and AstValueFactory per background thread loop,
rather than one per compile task, which allows us to reduce per-task
costs and re-use the AstValueFactory's string table and previous String
internalizations.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once

There's a bit more work to do to add support for import assertions for
dynamic import(). This is the first of a series of changes to do that.
This adds parser support for the form of import() that takes import
assertions per https://tc39.es/proposal-import-assertions/#prod-ImportCall
A future change will pass the assertions expression along to
Runtime_DynamicImportCall where the assertions will be unpacked and
filtered per Isolate::supported_import_assertions_.

Because of LocalHeap safepoints, our existing assert scopes don't
necessarily maintain the same guarantees as desired. In particular,
DisallowHeapAllocation no longer guarantees that objects don't move.
This patch transitions DisallowHeapAllocation to
DisallowGarbageCollection, to ensure that code using this scope is
also protected against safepoints.

Per https://tc39.es/proposal-import-assertions/#sec-assert-clause-to-assertions,
import assertions should be sorted by the import assertion [[Key]]s,
in order to prevent hosts from relying on a changing order of the
assertions to determine behavior.
Prior to this change, the assertions were being sorted by pointer. With
this CL, the keys are sorted using a code point ordering so that the
order of the assertions received by the host will be stable and
non-surprising.
This CL also switches the SourceTextModuleDescriptor's ModuleRequestMap,
RegularExportMap, and RegularImportMap to use the code point order
comparison rather than their former shortlex sort. This change will not
be externally visible, but it seems best to make these consistent.
In order to avoid #including the fairly large ast-value-factory.h
into ast/modules.h, I changed ImportAssertions into a separate class
definition rather than keeping it as a typedef. The alternative would
be to define a common AstRawStringComparer in ast-value-factory.h and
then #include ast-value-factory.h in both ast/modules.h and
parsing/parser.h so that the ImportAssertions typedef would have a
full, shared definition of the AstRawStringComparer type.

This change plumbs import assertions from SourceTextModuleDescriptor's
ModuleRequestMap into SourceTextModuleInfo via a new ModuleRequest
type, where previously there had been only the specifier.
SourceTextModuleDescriptor::module_map now deduplicates module requests
using the specifier and the import assertions. Continuing to use the
specifier alone would cause a loss of information in the event that
a module imports from the same specifier multiple times using different
sets of assertions. Failing to deduplicate at all would result in
multiple requests for statements like `import {a,b,c} from "foo.js"`,
which would be a potential performance issue. See design doc at
https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY
for more detail on this decision.
v8::internal::ModuleRequest holds the assertions as an array of the form
[key1, value1, position1, key2, value2, assertion2, ...]. However the
parser still needs to use a map, since duplicate assertion keys need to
be detected at parse time. A follow-up change will ensure that
assertions are sorted using a proper lexicographic sort.

Parse the AssertEntries in an import assertion clause, storing them in
a map. Plumb them through the parser to the appropriate
SourceTextModuleDescriptor methods.
The next change will plumb them into the SourceTextModuleDescriptor's
ModuleRequestMap and through to SourceTextModuleInfo::New.

This is the first change in the process of implementing import
assertions per https://tc39.es/proposal-import-assertions/.
This CR adds support for the empty form of the AssertClause.
Also added is a --harmony-import-assertions flag to enable/disable
import assertions. For now, the feature is off by default.
The next change will enable the parser to handle a non-empty list
of AssertEntries.

Remove error reporting from parsing::Parse*, since in most cases we
didn't actually want them (clear errors afterward), and there was an
issue where Compiler::Compile would try to report errors already
reported in ParseAny, which ended up triggering unreachable code.
As a drive-by, move some one-off parse exception handling in
test-parsing into a CHECKED_PARSE_PROGRAM macro which replaces all the
"necessarily positive" calls to parsing::ParseProgram.

Move rewriting, scope analysis, and internalization, to be unconditional
operations done after parsing rather than a separate compile phase. This
removes some of the complexity about rememberering when to call
Compiler::Analyze, and makes these paths a bit more uniform.
Also, forbid allocating any more AST strings after AstValueFactory
internalization, by nulling out the Zone. Add an InternalizePartial
method which doesn't null out the zone for those cases where we do want
to be able to allocate after internalizing (e.g. internalization before
scope analysis).

Move the persistent compilation state and Isolate inputs (such as the
allocator, shared AST constants, hash seed, logger, etc.) which survives
across both parse and compile, out of ParseInfo and into a new
UnoptimizedCompileState class. Also add UnoptimizedCompilePerThreadState
for per-thread state such as stack limit and RCS.
In particular, this new state survives the ParseInfo being destructed,
which means it is available after off-thread finalization. This allows a
followup to access the PendingCompilationErrorHandler after finalization
and report errors on merge.

> [parser] Introduce UnoptimizedCompileFlags
>
> UnoptimizedCompileFlags defines the input flags shared between parse and
> compile (currently parse-only). It is set initially with some values, and
> is immutable after being passed to ParseInfo (ParseInfo still has getters
> for the fields, but no setters).
>
> Since a few of the existing flags were output flags, ParseInfo now has a
> new output_flags field, which will eventually migrate to a ParseOutputs
> structure.
