Rich Kadel 12ddd6073a Fixed coverage map issues; better aligned with LLVM APIs
Found some problems with the coverage map encoding when testing with
more than one counter per function.

While debugging, I realized some better ways to structure the Rust
implementation of the coverage mapping generator. I refactored somewhat,
resulting in less code overall, expanded coverage of LLVM Coverage Map
capabilities, and much closer alignment with LLVM data structures, APIs,
and naming.

This should be easier to follow and easier to maintain.

This directory currently contains some LLVM support code. This will generally
be sent upstream to LLVM in time; for now it lives here.

NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never*
be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types
must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here.

Functions that return a failure status and leave the error in
the LLVM last error should return an LLVMRustResult rather than an
int or anything to avoid confusion.

When translating enums, add a single `Other` variant as the first
one to allow for new variants to be added. It should abort when used
as an input.

All other types must not be typedef-ed as such.
