      [inspector] use interrupt for pause only as last resort · 6d87d957
      Alexey Kozyatinskiy authored 
      With this CL we use interrupt for pause in two cases:
- when we process Debugger.pause on interruption,
- when we would like to break as soon as possible after OOM.
In all other cases, e.g. for async step into we use break
on function call by calling StepIn debugger action.

In mentioned cases we should not actually use interrupt as well:
- Debugger.pause in this case scheduled using interrupt and we
  may just break right now without requesting another interrupt,
  unfortunately blink side is not ready,
- we should use more reliable way to break right after near OOM
  callback, otherwise we can get this callback, increase limit,
  request break on next interrupt, before interrupt get another
  huge memory allocation and crash.

There are couple advantages:
- we get much better break locations for async stepping
  (see inspector tests expectations),
- we can remove DEBUG_BREAK interruption
  (it should speedup blackboxing with async tasks, see
  removed todo in debug.cc for details)
- it is required preparation step for async step out,
  (see https://chromium-review.googlesource.com/c/v8/v8/+/1054618)

      Normalize casing of hexadecimal digits · 822be9b2
      Mathias Bynens authored 
      This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

      [elements] Rename FAST elements kinds · 26c00f4a
      Mathias Bynens authored 
      The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.

This patch renames the FAST elements kinds as follows:

- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS

The following exceptions are left intact, for lack of a better name:

- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS

This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.
