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

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.

4337e70cca Prepare for leaky exceptions
Now toFormalType() reports errors by exceptions, they will be
sometimes leaked to the wider context.  This commits adds a catch.
