If a `do concurrent` loop is offloaded then there should be no CUDA data
transfer in it. Update the semantic and lowering to take that into
account.
`AssignmentChecker` has to be put into a separate pass because the
checkers in `SemanticsVisitor` cannot have the same `Enter/Leave`
functions. The `DoForallChecker` already has `Eneter/Leave` functions
for the `DoConstruct`.

This adds another puzzle piece for the support of OpenMP DECLARE
REDUCTION functionality.
This adds support for operators with derived types, as well as declaring
multiple different types with the same name or operator.
A new detail class for UserReductionDetials is introduced to hold the
list of types supported for a given reduction declaration.
Tests for parsing and symbol generation added.
Declare reduction is still not supported to lowering, it will generate a
"Not yet implemented" fatal error.
Fixes #141306
Fixes #97241
Fixes #92832
Fixes #66453

constructs (#125750)
Previous patch was too restrictive and didn't take into account cuf
kernels and openacc compute constructs as being device context.

The infrastructure in semantics that is used to check that the
left-hand sides of normal assignment statements are really definable
variables was not being used to check whether the LHSs of pointer assignments
are modifiable, and so most cases of unmodifiable pointers are left
undiagnosed. Rework the semantics checking for pointer assignments,
NULLIFY statements, pointer dummy arguments, &c. so that cases of
unmodifiable pointers are properly caught. This has been done
by extracting all the various definability checking code that has
been implemented for different contexts in Fortran into one new
facility.
The new consolidated definability checking code returns messages
meant to be attached as "because: " explanations to context-dependent
errors like "left-hand side of assignment is not definable".
These new error message texts and their attached explanations
affect many existing tests, which have been updated. The testing
infrastructure was extended by another patch to properly compare
warnings and explanatory messages, which had been ignored until
recently.

Have CheckDefinabilityInPureScope and CheckCopyabilityInPureScope return
false when their checks fail and report errors so that we will be able
to avoid reporting extra errors in those cases.
