39ad705c13 LibJS: Use the new is_ascii_foo() helpers from AK
These constexpr helpers generate nicer code than the LibC ctype.h
variants, so let's make use of them. :^)

0e10dec324 LibJS: Parse only AssignmentExpressions in ComputedPropertyNames
The property name in an object literal can either be a literal or a
computed name, in which case any AssignmentExpression can be used, we
now only parse AssignmentExpression instead of the previous incorrect
behaviour which allowed any Expression (Specifically, comma
expressions).

8b3f8879c1 LibJS: Use an enum class instead of 'bool is_generator'
This avoid confusion in the order of the multiple boolean parameters
that exist.

17da54d49c LibJS: Fix two accidentally incorrect ScriptFunction constructions
The addition of an is_generator parameter broke this, as is_strict was
being passed in, causing an assertion.
This is being addressed by changing it to an enum in #7981, but in the
meantime let's just fix these two cases.

ea7ba34a31 AK+LibWasm+LibJS: Disallow Variant.has() on types that aren't contained
Checking for this (and get()'ing it) is always invalid, so let's just
disallow it.
This also finds two bugs where the code is checking for types that can
never actually be in the variant (which was actually a refactor
artifact).

Otherwise we'd be spinning there forever.

60064e2049 LibJS: Make invalid RegExp flags a SyntaxError at parse time
This patch changes the validation of RegExp flags (checking for
invalid and duplicate values) from a SyntaxError at runtime to a
SyntaxError at parse time - it's not something that's supposed to be
catchable.
As a nice side effect, this simplifies the RegExpObject constructor a
bit, as it can no longer throw an exception and doesn't have to validate
the flags itself.

c93c2dc72c LibJS: Rename RegExpLiteral m_content to m_pattern
This is what we call it elsewhere, let's be consistent.

2b4c2301a9 LibJS: Stop rolling back parser state that is immediately replaced
This showed up on a profile (barely), so should help a tiny bit with
perf in parsing arrow functions.

b91c49364d AK: Rename adopt() to adopt_ref()
This makes it more symmetrical with adopt_own() (which is used to
create a NonnullOwnPtr from the result of a naked new.)

0255c8d976 Only apply auto-naming of function expressions based on syntax
The auto naming of function expressions is a purely syntactic
decision, so shouldn't be decided based on the dynamic type of
an assignment. This moves the decision making into the parser.

One icky hack is that we add a field to FunctionExpression to
indicate whether we can autoname. The real solution is to actually
generate a CompoundExpression node so that the parser can make
the correct decision, however this would have a potentially
significant run time cost.

This does not correct the behaviour for class expressions.

Patch from Anonymous.

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
