- Removed duplication and unnecessary indirection from all suites testcfgs.
- Introduced a more comprehensive context to cover both command context and other platform specific concerns.
- Propagated above context to TestLoader to allow for test counting command execution on all platforms.
- Wrapped original pool with another class to give it a new interface and allow injecting different implementations in the future.
- Consolidated progress indicators under a single processor in the pipeline.
- Consolidated result retention requirements calculation outside of pipeline chain.
- Refactored LoaderProc and got it under tests.
- Added some more tests for the standard runner.
- Extracted BuildConfig class.

The error message held in {CompilationResult} was not null-terminated,
leading to ASan complaints. Just store it in a {std::string} and use
{c_str()} to get a properly null-terminated C-string.

This adds a first simple version of the inspector fuzzer, which is a
stripped-down version of the inspector-test executable. The fuzzer
generates inputs which are compatible with inspector-test.
There are still memory leaks, and the fuzzer will probably run into
timeouts most of the time. Both of this will be addressed in follow-ups.

This is the beginning of a new fuzzer that generates
correct-by-construction Wasm modules. This should allow us to better
exercise the compiler and correctness aspects of fuzzing. It is based off
of ahaas' original Wasm fuzzer.
At the moment, it can generate expressions made up of most binops, and
also nested blocks with unconditional breaks. Future CLs will add
additional constructs, such as br_if, loops, memory access, etc.
The way the fuzzer works is that it starts with an array of arbitrary
data provided by libfuzzer. It uses the data to generate an expression.
Care is taken to make use of the entire string. Basically, the
generator has a bunch of grammar-like rules for how to construct an
expression of a given type. For example, an i32 can be made by adding
two other i32s, or by wrapping an i64. The process then continues
recursively until all the data is consumed.
We generate an expression from a slice of data as follows:
* If the slice is less than or equal to the size of the type (e.g. 4
bytes for i32), then it will emit the entire slice as a constant.
* Otherwise, it will consume the first 4 bytes of the slice and use
this to select which rule to apply. Each rule then consumes the
remainder of the slice in an appropriate way. For example:
* Unary ops use the remainder of the slice to generate the argument.
* Binary ops consume another four bytes and mod this with the length
of the remaining slice to split the slice into two parts. Each of
these subslices are then used to generate one of the arguments to
the binop.
* Blocks are basically like a unary op, but a stack of block types is
maintained to facilitate branches. For blocks that end in a break,
the first four bytes of a slice are used to select the break depth
and the stack determines what type of expression to generate.
The goal is that once this generator is complete, it will provide a one
to one mapping between binary strings and valid Wasm modules.

Depending on the inputs the fuzzer creates multiple functions. These
functions can have signatures with an int32 return value and up to three
parameters of type int32, int64, float32, or float64.

This CL adds fuzzers for the wasm module sections 'types', 'names',
'globals', 'imports', 'function signatures', 'memory', and 'data', one
fuzzer per section. No fuzzers are added for the other sections because
either there already exists a fuzzer (e.g. wasm-code), or there exist
inter-section dependencies.
To avoid introducing a bunch executables which would make compilation
with make slow, I introduce a single executable
'v8_simple_wasm_section_fuzzer' which calls the fuzzers mentioned above.
This executable is run by the trybots and ensures that the fuzzers
actually compile. For debugging I introduce commandline parameters which
allow to execute the specific fuzzers from 'v8_simple_wasm_section_fuzzer'.
