[flang][driver] Add options for unparsing
This patch adds the following compiler frontend driver options:
* -fdebug-unparse (f18 spelling: -funparse)
* -fdebug-unparse-with-symbols (f18 spelling: -funparse-with-symbols)
The new driver will only accept the new spelling. `f18` will accept both
the original and the new spelling.
A new base class for frontend actions is added: `PrescanAndSemaAction`.
This is added to reduce code duplication that otherwise these new
options would lead to. Implementation from
* `ParseSyntaxOnlyAction::ExecutionAction`
is moved to:
* `PrescanAndSemaAction::BeginSourceFileAction`
This implementation is now shared between:
* PrescanAndSemaAction
* ParseSyntaxOnlyAction
* DebugUnparseAction
* DebugUnparseWithSymbolsAction
All tests that don't require other yet unimplemented options are
updated. This way `flang-new -fc1` is used instead of `f18` when
`FLANG_BUILD_NEW_DRIVER` is set to `On`. In order to facilitate this,
`%flang_fc1` is added in the LIT configuration (lit.cfg.py).
`asFortran` from f18.cpp is duplicated as `getBasicAsFortran` in
FrontendOptions.cpp. At this stage it's hard to find a good place to
share this method. I suggest that we revisit this once a switch from
`f18` to `flang-new` is complete.
