Jon Ross-Perkins b1ee45c1e4 Extract ParseAndExecute as its own library. (#2813) 
Currently ParseAndExecute-style logic is done in main.cpp and a test. #2799 is adding another test that needs it, as is #2811.

Also more clearly marks fuzzing as testing.

This is being extracted out of #2799 in order to try unblocking progress while review continues.

Jon Ross-Perkins d12583fc08 Do cleanup on explorer fuzzing infrastructure. (#2790) 
I'm partly doing this because the current setup would be difficult to share with the toolchain. e.g., ProtoToCarbon isn't explorer-specific, but the only way to run it via CLI is the explorer's fuzzverter. I want a separate tool.

This change:

- Adds a //common/fuzzing:proto_to_carbon tool.
  - The rest of fuzzverter is now just //explorer/fuzzing:ast_to_proto.
  - The change simplifies overall handling and removes a LLVM CLI dependency.
- Stops allowing unknown fields in the proto.
  - This has mostly led to forgetting to remove fuzzer inputs that were for removed features.
- Moves more non-explorer-specific bits to //common/fuzzing.
- Cleans up remaining pieces in //explorer/fuzzing
  - Merges the //explorer/fuzzing proto tests, which deduplicates AstToString copies.
    - These tests also had duplicate dependencies, etc -- and all complete in ~6s.
  - Updates and fixes regen_corpus which was previously broken by other changes.
  - Updates the README to reflect changes.
- Removes obsolete proto-fuzzer build configuration (AFAICT this is no longer needed).

Richard Smith 4fa71e32f5 Add support for most kinds of declarations to be declared and used as namespace members (#2575) 
Support for global variables is still missing; they're a bit more tricky because they use a pattern to introduce their name.

Prior to this change, explorer heavily relied on name comparisons to determine whether two declarations declare the same entity. Some of those instances are fixed in this PR, but more remain to be fixed, and some TODOs are added for some harder-to-fix instances.

pk19604014 98d95cd188 Cleanup: since explorer_fuzzer is now a standard cc_fuzz_test, and runs on all files in the corpus, there's no need for fuzzer_util_test to do the same manually 
Before:
```
//explorer/fuzzing:fuzzer_util_test                                      PASSED in 18.5s
```

After:
```
//explorer/fuzzing:fuzzer_util_test                                      PASSED in 0.3s
```

pk19604014 98f4bb3110 Changed fuzzer_util_test to not process the full fuzzer corpus, but instead just run on a single file, to minimize friction when making fuzzer proto changes (#1354) 
At least one successful parse is still required for the test to pass.

pk19604014 ed93d95fce Allow unknown fields in fuzzing text proto (#1296) 
This is to help with frequent build breakages cased by proto changes.
Fuzzer corpus can be periodically auto-regenerated.
Crashing samples from the fuzzer are better 'preserved' in the form of fail_xx.carbon tests.

pk19604014 cdc9428984 Changed the type of parameter in FunctionType ctor from generic Expression to TupleLiteral to match the grammar (#1272) 2022-05-20 17:36:17 -07:00
Jon Meow 3b8d4a4910 Adjust test to work in more environments. (#1231) 
The current test is really testing too closely to bazel internals.

pk19604014 150057f260 Added GetRunfilesFile() to be able to reliably determine prelude location under various invocation scenarios 
The logic is using bazel Runfiles API per Jon's suggestion.

One of the scenarios used by the fuzzing framework is to place the binary and its runfiles into a folder, resulting in a directory layout like this:

[temp dir]
fuzzer
fuzzer.runfiles/

Tested:
bazel test -c opt explorer/fuzzing:explorer_fuzzer
bazel build -c opt explorer/fuzzing:explorer_fuzzer + run the binary from various locations
