Jon Meow 2e9e4f4cb3 Migrate remaining exits to FATAL_*_ERROR calls (#704)
Adds FATAL for things that are most likely programming errors in executable_semantics.

Jon MeowandChandler Carruth f0af3cb795 Switch from llvm::errs()+exit() to FATAL_USER_ERROR() stream-based handling. (#670)
This is intended to:

- Standardize use of line_num (and highlight where no line_num is available).
- Standardize indications of runtime/compilation errors.
- Make it incrementally easier to write new errors.

Jon Meow edbc3f7716 Use llvm::ListSeparator for simpler separators (#671)
I was looking for something like this, I think it's a straightforward simplification for code. Internally, it handles skipping the separator on the first print.

Jon Meow 8fccecadeb Refactor output to be more streaming-focused. (#666)
- Switch code to llvm::raw_ostream as part of standardizing output forms.
    - Preferring llvm::raw_ostream over std::ostream because other tooling code should be expected to rely on llvm more closely, and an overall preference towards library consistency.
    - There are a couple spots in syntax/ that still use std streams, but I'd prefer to take a separate PR to see how best to address those.
    - std::boolalpha doesn't work with llvm, so I've implemented equivalent in a couple places (not enough that it felt like worth making a helper function).
- Implement Print(ostream) as consistently as we can, as an instance member.
    - This facilitates the use of the common/ostream.h template to provide operators.
    - Preferring this approach so that Print is easily accessible via gdb, per suggestion on #executable-semantics.
- Switch code currently calling `type->Print(ostream)` to instead do `ostream << *type`.
- Remove the unused `PrintTypeEnv`, nothing used it and the declaration didn't match the definition.

Geoff RomerandJon Meow d5124256a2 Split interpreter into smaller modules (#662)
- Move Heap and Frame/Scope to their own headers.
- Move some functions to more appropriate headers (e.g. CopyValue -> value.h).
- Define a separate Bazel rule for each header/cpp pair.
- Modify PrintValue to not print the frames of a ContinuationValue. This was necessary to break a dependency cycle between PrintValue, PrintFrame, and Action::Print.
