This CL fixes a long standing issue where reentering TimedHistograms
scopes would cause spurious measurements. Only the non-nested scopes
yielded correct results.
Due to the changed numbers, the V8.Execute histogram is renamed to
V8.ExecuteMicroSeconds. Note that this histogram is also guarded
behind the --slow-histograms flag due to the additional overhead.
Unlike before, it does no longer include time for external callbacks
and only measures self time. The following example illustrates the
new behaviour:
1. Enter V8: |--+.......+--| self-time: 4 units (reported)
2. Exit V8 (callback): |-+...+-| self-time: 2 units (ignored)
3. Re-enter V8: |---| self-time: 3 units (reported)
This would result in 2 histogram entries with 4 time units for the first
V8 slice and 3 units for the nested part. Note that the callback time
itself is ignored.
This CL attempts to clean up how TimedHistograms work:
- Histogram: the base class
- TimedHistograms: used for time-related histograms that are not nested
- NestedTimeHistograms: Extends TimedHistograms and is used for nested
histograms
This CL changes Histograms to not measure time themselves. Measurements
happen in the *HistogramScopes:
- BaseTimedHistogramScope: Base functionality
- TimedHistogramScope: For non-nested measurements
- NestedTimedHistogramScope: For nested measurements
- PauseNestedTimedHistogramScope: Ignore time during a given scope.
This is used to pause timers during callbacks.
Additional changes:
- ExternalCallbackScope now contains a PauseNestedTimedHistogramScope
and always sets VMState<EXTERNAL>

This also inverts the dependency between src/inspector:inspector and

In an effort to merge `CODE_SPACE_WRITE_SCOPE` and
`NativeModuleModificationScope`, this CL moves the interface and
implementation of the latter into code-space-access.{h,cc}, where the
former already lives. No other changes to the code itself.

The adding of base:: was mostly prepared using git grep and sed:
git grep -l <pattern> | grep -v base/vector.h | \
xargs sed -i 's/\b<pattern>\b/base::<pattern>/
with lots of manual clean-ups due to the resulting
v8::internal::base::Vectors.
#includes were fixed using:
git grep -l "src/utils/vector.h" | \
axargs sed -i 's!src/utils/vector.h!src/base/vector.h!'

`bazel build :d8 --no//:v8_enable_webassembly`

Command to build: `bazel build :d8`
Caveats:
- Needs clang
- Only supports x64 on Linux
- Bare V8: no Wasm and no ICU
- Still needs GN to generate inspector files
