Allow modules of both kinds with the same name to be used in
the same source file (but not in the same scoping unit, a
constraint of the standard that is now enforced).
The symbol table's scope tree now has a single instance of
a scope with a new kind, IntrinsicModules, whose children are
the USE'd intrinsic modules (explicit or not). This separate
"top-level" scope is a child of the single global scope and
it allows both intrinsic and non-intrinsic modules of the same

The search path directories need to make a distinction between

This builder exposed a somehow "unsafe" API: it pretends we can
construct an InsertOnRangeOp from a range of SSA values, even though
this will crash if these aren't the result of `arith.constant` since
the operation actually needs attribute values (a build method can't
fail gracefully).
That means that the caller must check for the producer, at which
point they can just assemble the attribute array directly and call
the existing builder.
The existing call-sites were even in a worse state here: they would
actually create a constant operation that wouldn't be used and only
serve to carry the attribute through the builder API.

This is a set of type building models that is specific to the lowering
process. It provides the mechanism of mapping C(++) header file interfaces
to the MLIR+FIR type system.
It also provides some macros to build a constexpr evaluated table to
runtime functions. This code is used to build the interface tables to
various runtime support libraries.

The bridge uses internal boxes of related ssa-values to track all the
information associated with a Fortran variable. Variables may have a
location and a value, but may also carry other properties such as rank,
shape, LEN parameters, etc. in Fortran.

The symbol map is a data structure for tracking variables in a subprogram during the lowering of that subprogram to FIR/MLIR. These data structures will be used by the bridge, which has not been upstreamed yet.

This upstreams the internal name mangling used in the bridge to generate
unique names from symbols.
Replace InternalNamesTest with the actual, functional unittest.

The complex expression helper class can be used to generate small,
short-lived instances of a "helper" that can be used to aid the
construction of complex expressions in FIR. The helper class bundles
together these functionally related operations.
Included in this diff is the header for the FIR builder. The
implementation has other dependences and will follow.

Part of lowering is to convert the front-end types to their FIR dialect representations. These conversions are done by here in the ConvertType module.
proactively update the code to conform better with LLVM coding conventions

The lowering bridge will call these lowering hooks to process the Open
MP directives that it iterates over in the PFT. This is a mock
interface without an implementation in this patch.

structure for upstreaming to llvm-project.
These files have had many changes since they were originally upstreamed.
Some of the changes are cosmetic. Most of the functional changes were
done to support the lowering of control-flow syntax from the front-end
parse trees to the FIR dialect.
This patch is meant to be a reviewable size. The functionality it
provides will be used by code yet to be upstreamed in lowering.

[review D80449][NFC] make PFT ParentVariant a ReferenceVariant
ReferenceVariant had to be slightly updated to also support
non constant references (which is required for ParentType).
