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.
