Andrzej Warzynski 6f8ef1d6e8 [flang][driver] Add actions that execute despite semantic errors 
This patch adds a new abstract class for frontend actions:
`PrescanAndSemaDebugAction`. It's almost identical to
`PrescanAndSemaAction`, but in the presence of semantic errors it does
not skip the corresponding `ExecuteAction` specialisation. Instead, it
runs it as if there were no semantic errors. This class is for developer
actions only (i.e.  front-end driver options).

The new behaviour does not affect the return code from `flang-new -fc1`
when the input file is semantically incorrect. The return code is
inferred from the number of driver diagnostics generated in
`CompilerInstance::ExecuteAction` and this patch does not change that.
More specifically, the semantic errors are still reported and hence the
driver is able to correctly report that the compilation has failed (with
a non-zero return code).

This new base class is meant for debug actions only and
`DebugDumpAllAction` is updated to demonstrate the new behaviour. With
this change, `flang-new -fc1 -fdebug-dump-all` dumps the parse tree and
symbols for all input files, regardless of whether any semantic errors
were found.

This patch addresses https://bugs.llvm.org/show_bug.cgi?id=52097.
