These dependencies were introduced via the `ParseTreeDumper` API in:
* https://reviews.llvm.org/D96716
They manifested themselves in buildbot builders that set
`BUILD_SHARED_LIBS` to `On`.
Add the following options:
* -fdebug-dump-symbols
* -fdebug-dump-parse-tree
* -fdebug-dump-provenance
Summary of changes:
- Add 3 new frontend actions: DebugDumpSymbolsAction, DebugDumpParseTreeAction and DebugDumpProvenanceAction
- Add a unique pointer to the Semantics instance created in PrescanAndSemaAction
- Move fatal semantic error reporting to its own method, FrontendActions#reportFatalSemanticErrors
- Port most tests using `-fdebug-dump-symbols` and `-fdebug-dump-parse-tree` to the new driver if built, otherwise default to f18

Fortran 2018 explicitly permits an ignored type declaration
for the result of a generic intrinsic function. See the comment
added to Semantics/expression.cpp for an explanation of why this
is somewhat dangerous and worthy of a warning.

The intrinsic procedure table properly classify the various
intrinsics, but the PURE and ELEMENTAL attributes that these
classifications imply don't always make it to the utility
predicates that test symbols for them, leading to spurious
error messages in some contexts. So set those attribute flags
as appropriate in name resolution, using a new function to
isolate the tests.
An alternate solution, in which the predicates would query
the intrinsic procedure table for these attributes on demand,
was something I also tried, so that this information could
come directly from an authoritative source; but it would have
required references to the intrinsic table to be passed along
on too many seemingly unrelated APIs and ended up looking messy.
Several symbol table tests needed to have their expected outputs
augmented with the PURE and ELEMENTAL flags. Some bogus messages
that were flagged as such in test/Semantics/doconcurrent01.f90 were
removed, since they are now correctly not emitted.

It's possible to define a procedure that has a procedure dummy argument which
names the procedure that contains it. This was causing the compiler to fall
into an infinite loop when characterizing a call to the procedure.
Following a suggestion from Peter, I fixed this be maintaining a set of
procedure symbols that had already been seen while characterizing a procedure.
This required passing a new parameter to the functions that characterized a
Procedure, a DummyArgument, and a DummyProcedure.
I also added several tests that will crash the compiler without this change.

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.

The following _action_ options are always used with `-fsyntax-only`
(also an _action_ option):
* -fdebug-dump-symbols
* -fdebug-dump-parse-tree
This patch makes the above options imply `-fsyntax-only`.
From the perspective of `f18` this change saves typing and is otherwise
a non-functional change. But it will simplify things in the new driver,
`flang-new`, in which only the last action option is taken into account
and executed. In other words, the following would only run
`-fsyntax-only`:
```
flang-new -fdebug-dump-symbols -fsyntax-only <input>
```
whereas this would only run `-fdebug-dump-symbols`:
```
flang-new -fsyntax-only -fdebug-dump-symbols <input>

MLIRContext allows its users to access directly to the DialectRegistry it
contains. While sometimes useful for registering additional dialects on an
already existing context, this breaks the encapsulation by essentially giving
raw accesses to a part of the context's internal state. Remove this mutable
access and instead provide a method to append a given DialectRegistry to the
one already contained in the context. Also provide a shortcut mechanism to
construct a context from an already existing registry, which seems to be a
common use case in the wild. Keep read-only access to the registry contained in
the context in case it needs to be copied or used for constructing another
context.
With this change, DialectRegistry is no longer concerned with loading the
dialects and deciding whether to invoke delayed interface registration. Loading
is concentrated in the MLIRContext, and the functionality of the registry
better reflects its name.

OpenMP tests that include `use omp_lib` or run `test_symbols.sh` have not been updated as they require options `-intrinsic-module-directory` and `-funparse-with-symbols` which are currently not implemented in the new driver.
