e538054e6d [Assembler] Make fatal assembler errors non-fatal
Currently, if the assembler encounters an error after parsing (such as an
out-of-range fixup), it reports this as a fatal error, and so stops after the
first error. However, for most of these there is an obvious way to recover
after emitting the error, such as emitting the fixup with a value of zero. This
means that we can report on all of the errors in a file, not just the first
one. MCContext::reportError records the fact that an error was encountered, so
we won't actually emit an object file with the incorrect contents.

d3aa988471 MC: remove unnecessary restriction on tests
Rafael correctly pointed out that the restriction is unnecessary.  Although the
tests are intended to ensure that we dont abort due to an assertion, running the
tests in all modes is better since it also ensures that we dont crash without
assertions.  Always run these tests to ensure that we can handle invalid input
correctly.

d6d4c30745 MC: formalise some assertions into proper errors
Now that clang can be used as an assembler via the IAS, invalid assembler inputs
would cause the assertions to trigger.  Although we cannot recover from the
errors here, nor provide caret diagnostics, attempt to handle them slightly more
gracefully by reporting a fatal error.
