Character literals can be formatted using octal or hex escapes for
non-ascii characters. This is so that the program can be unparsed for
either pgf90 or gfortran to compile. But modfiles should not be affected
by that -- they should be consistent.
This changes causes modfiles to always have character literals formatted
with octal escapes.

This patch is enabling the generation of clauses enum sets for semantics check in Flang through

Summary:
When a program unit creates a generic based on one defined in a module, the
function `CopyFrom()` is called to create the `GenericDetails`. This function
copied the `specificProcs_` but failed to copy the `bindingNames_`. If the
function `CheckGeneric()` then gets called, it tries to index into the empty
binding names and causes the crash.
I fixed this by adding code to `CopyFrom()` to copy the binding names.
I also added a test that causes the crash.

This change implements support for image selectors and image selector
specifications as described in section 9.6.
In check-coarray[.h,cpp] I changed the `Leave()` function for
`parser::ImageSelectorSpec` to take a `parser::ImageSelector`, which
contains a list of image selector specifications. This allows us to
detect when the same specification is used more than once. I also added
code to analyze the expressions for the image selector specifications to
expression.cpp and a test for all of the conditions to check at
compile-time.
Note that we do not check at compile-time to see if the value of the
cosubscripts are within the specified cobounds. We also do not check anything
related to selecting a valid team. We also do not check that the denotation of
the `stat-variable` is not dependent on the evaluation of an entity in the
same statement.

Summary:
A program may erroneously reference the same name as both a data object
and as a function. Some of these references were causing an internal
error in expression analysis.
It was already the case that a symbol referenced in a parse tree for a
call was changed from an `Entity` to a `ProcEntity`. I added code to
detect when a symbol was referenced in a parse tree as an array element
gets changed from an `Entity` to an `ObjectEntity`. Then, if an
`ObjectEntity` gets called as a function or a `ProcEntity` gets
referenced as a data object, errors get emitted.
This analysis was previously confined to the name resolution of the
specification part of a `ProgramTree`. I added a pass to the execution
part of a `ProgramTree` to catch names declared in blocks.

G++ 10.1 emits inappropriate "use of uninitialized data" warnings when

whose multiple instantiations magnified the number of warnings.
These changes dodge those warnings by making some innocuous changes to
the code. In the parser, the idiom defaulted(cut >> x), which yields a
parser that always succeeds, has been replaced with a new equivalent
pass<T>() parser that returns a default-constructed value T{} in an
arguably more readable fashion. This idiom was the only attestation of
the basic parser cut, so it has been removed and the remaining code
simplified. In Evaluate/traverse.h, a return {}; was replaced with a

Summary:
If you create an expression with parse errors, the `parser::Expr.typedExpr`
will be empty, which causes a compiler crash. The crash is caused by the
check in check-do-forall.cpp that scans all expresssions to see if `DO`
variables are being modified.
It turned out that the problem was that I was fetching subexpressions of type
`parser::Expr`, which are not guaranteed to have a non-null `typedExpr`. I
fixed this by only grabbing the top-level expression from which to gather
arguments as part of the DO loop analysis. This, in turn, exposed a problem
where I wasn't collecting all of the actual arguments in an expression. This
was caused by the fact that I wasn't recursing through the rest of the
expression after finding an argument. I fixed this by recursing through the
argument in the member function in `CollectActualArgumentsHelper`.
