fir.array_update is only handling intrinsic assignments.
They are two big differences with user defined assignments:
1. The LHS and RHS types may not match, this does not play well
with fir.array_update that relies on both the merge and the
updated element to have the same type.
2. user defined assignment has a call semantics, with potential
side effects. So if a fir.array_update can hide a call, it traits
would need to be updated.
Instead of hiding more semantic in the fir.array_update, introduce
a new fir.array_modify op that allows de-correlating indicating that
an array value element is modified, and how it is modified.
This allow the ArrayValueCopy pass to still perform copy elision
while not having to implement the call itself, and could in general
be used for all kind of assignments (e.g. character assignment).
Update the alias analysis to not rely on the merge arguments (since
fir.array_modify has none).
Instead, analyze what is done with the element address.
This implies adding the ability to follow the users of fir.array_modify,
as well as being able to go through fir.store that may be generated to
store the RHS value in order to pass it to a user define routine.
This is done by adding a ReachCollector class to gather all array
accesses.

The THEN keyword in the "ELSE IF (test) THEN" statement is useless
syntactically, and to omit it is a common error (at least for me!)
that has poor error recovery. This patch changes the parser to

According to OpenMP 5.0 spec document, the following semantic restrictions have been dealt with in this patch.
1. [sections construct] Orphaned section directives are prohibited. That is, the section directives must appear within the sections construct and must not be encountered elsewhere in the sections region.
Semantic checks for the following are not necessary, since use of orphaned section construct (i.e. without an enclosing sections directive) throws parser errors and control flow never reaches the semantic checking phase. Added a test case for the same.
2. [sections construct] Must be a structured block
Added test case and made changes to branching logic
3. [simd construct] Must be a structured block / A program that branches in or out of a function with declare simd is non conforming
4. Fixed !$omp do's handling of unlabeled CYCLEs
