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.

58e75c7a48 Unimplemented features moved to their own exception (#1361)
Unimplemented features moved to their own exception

InternalCompilerError is an exception that really should be reserved for
actual internal errors of the compiler.  Unimplemented features can now
use either solUnimplemented( ) or, if it should be conditional, then
solUnimplementedAssert( ).

* Revert some unimplemented exceptions, add handlers

The jsonCompiler and CommandLineInterface needed handlers for the
new UnimplementedFeatureException, and some cases I had moved on to
the new exception were better treated as real internal compiler
errors.

* Standardize on "Unimplemented feature" message

4524ad0870 Add support for do/while loops
This commit adds support for a standard do <statement> while <expr>;
form of statement.  While loops were already being supported; supporting
a do/while loop mostly involves reusing code from while loops but putting
the conditional checking last.
