Whenever we are adding a new AddressRegion to the CodeMap, we first
remove all overlapping regions. The logic to check for overlapping
region is incomplete. For example, if all existing regions are less than
the region to be added, we incorrectly remove all regions, effectively
deleting all JITCodeEntry we have constructed.

We extract this overlapping check into a helper function, so that we can
unittest this without worrying about JITCodeEvent functionality, and also
without dealing with V8 internals (like Isolate and SFI).

The overlapping logic is rather hard to understand, has many special
cases, it will probably be much easier to just loop through all the
entries, rather than using lower_bound. Ideally, we can refactor this to
use some sort of sweep-line algorithm. Hopefully the unittests catch the
most obvious cases.

- Introduce helper to push arguments onto the stack (Standalone this
change doesn't make a lot of sense, but is in preparation for including
the receiver in argc).
- Introduce helper to shift arguments already on the stack to make room
for new arguments (Varargs).
- arm64 is not included because a) there was already a helper similar
to ShiftArguments and b) PushArguments is not similar enough to make
sense for arm64 because of small differences (e.g. also pushing the
function) in conjunction with stack alignment.

It must be possible to determine an object's size on the heap without
relying on the presence of any other objects. Specifically, if an
object and its WasmTypeInfo die at the same time, they can be swept
in any order, and the sweeper may need to know their sizes.
This patch solves the problem by repurposing two bytes in the Map,
where WasmStructs can store their instance size, and WasmArrays can
store their element size (which can be used to compute their size).

Passing directories to fopen is not a defined behaviour in C/C++.
A new test case added by https://crrev.com/c/3098189 is trying to
import directories which is expected to fail.

Test however is not passing on some platforms including on S390 Linux
as `fopen` is successful, size gets set to 0 and a (non-existent)
empty file gets returned.

This CL uses `stat` to make sure the path is valid and is
not a directory.

The JSRegExp heap object should not be the source of truth for regexp
flags, which are also relevant in places that don't need or want to
care about the heap object layout (e.g.: the regexp parser).

Introduce RegExpFlags as a new source of truth, and base everything
else on these flags.

As a first change, remove the js-regexp.h dependency from the regexp
parser. Other files in src/regexp/ should be updated in follow-up
work.

This adds the option to list disallowed flags for differential
fuzzing directly in the harness. Flags that can crash in smoke
tests shoule be added there.

After building V8 using Clang (./out/x64.release/v8_build_config.json
says that "is_clang" is true), I could reproduce the referenced bug
report locally. Replacing the getMinutes() calls with getUTCMinutes()
calls fixed the test failure.

.. instead of a FlatStringReader. This is in preparation for reusing
the regexp parser directly from the JS parser, which uses different
string types (AstRawString instead of heap Strings).

Drive-by: Hide parser internals in the .cc file.
