89b60ffbd4 Refactor error reporting
This commit introduces ErrorReporter, a utility class which consolidates
all of the error logging functionality into a common set of functions.
It also replaces all direct interactions with an ErrorList with calls to
an ErrorReporter.

This commit resolves issue #2209

9bcbd93ac5 Change translation of implicit throws (issue #1589).
This adds a new invalid instruction that is used for encoding
implicit throws that are emitted by the compiler. This makes it
possible to distinguish such runtime errors from user-provided,
explicit throws.

1f30982ab5 Use fully-qualified names for linking, too
Using libraries leaves behind a library link reference in the binary
which the linker must later resolve.  These link references were still
being generated by name and not by fully-qualified name.  This would
lead to a link-time collision between two libraries having the same
name but in different source units.

This change changes linker symbols over to fully-qualified names,
which resolves that issue.  This does potentially introduce a new
problem, which is that linker symbols appear to be limited to 36
characters and are truncated.  Storing paths extends the average
symbol size, and it would be great if truncation was from the tail
rather than the head.
