2c9c57c061 Only profiling when it's enabled. (#121404)
Summary:
The profiling, even when disabled, takes up about 1.5% cpu for a model I'm looking into.

This patch just splits into with/without profile runs.

The potential downside is that now the script can't enable profiling in itself. It doesn't seem to be used anywhere. If that's a crusial usecase, we can do something about it but ideally we wouldn't.

Test Plan:

b34b192d6b Reland "Make debug_pkl smaller by only emitting unique traces." (#73368)
Summary:
## Original commit message:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73368

debug_pkl file inside of pytorch's .pt file consists of a list of SourceRanges. Each SourceRange points to a Source which is a stack track, filename, and start, end numbers. Those are emitted in debug_pkl file as strings.
Since many SourceRange shares the same source, the string for trace can be deduped.
The newer format saves a set of unique traces in a tuple, then each SourceRange will save the offset of it's trace w.r.t. position in that tuple. (i.e. manually applying dictionary compression).
The above helps with smaller file size. On loading, if we copy each trace to Source as string the runtime memory would still blowup.
To mitigate this, we use SourceView directly instead of source which will take the reference of string inside of Deserializer and make that into string_view. This is safe because Deserializer is hold by Unpickler by shared_ptr, and Unpickler is also hold by shared_ptr by another Source object. That Source object will be alive during the model construction.

Summary:
Delete `-Wno-unused-variable` from top level `CMakeLists.txt`
Still suppress those warnings for tests and `torch_python`

Delete number of unused variables from caffe2 code
Use `(void)var;` to suppress unused variable in range loops
Use `C10_UNUSED` for global constructors and use `constexpr` instead of `static` for global constants

Do not delete `caffe2::OperatorBase::Output` calls as they have side effects

034a238bab [jit] Implement ScriptProfile to collect instruction profiles. (#57397)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/57397

Introduces two main classes in C++ runtime:

ScriptProfile is the implementation for enalbing and disabling interpreter
profiling in C++. This should be only used from Python, and we will add
corresponding Python API in the next diff.

InstructionSpan is a utility class to instrument execution of each single
instruction. A start timestamp is recorded in the consturctor, and an end
timestamp is recorded in the destructor. During destruction, this will send
runtime data to all enabled ScriptProfile instances.

Test Plan:
build/bin/test_jit --gtest_filter='ScriptProfileTest.Basic'
