Jean Perier 7c158e3e55 [flang] add evaluate::IsAllocatableDesignator helper
Previously, some semantic checks that are checking if an entity is an
allocatable were relying on the expression being a designator whose
last symbol has the allocatable attribute.

This is wrong since this was considering substrings and array sections of
allocatables as being allocatable. This is wrong (see NOTE 2 in
Fortran 2018 section 9.5.3.1).

Add evaluate::IsAllocatableDesignator to correctly test this.
Also add some semantic tests for ALLOCATED to test the newly added helper.
Note that ifort and nag are rejecting coindexed-named-object in
ALLOCATED (`allocated(coarray_scalar_alloc[2])`).
I think it is wrong given allocated argument is intent(in) as per
16.2.1 point 3.
So 15.5.2.6 point 4 regarding allocatable dummy is not violated (If the actual
argument is a coindexed object, the dummy argument shall have the INTENT (IN)
attribute.) and I think this is valid. gfortran accepts it.

The need for this helper was exposed in https://reviews.llvm.org/D122779.

Jean Perier ec13942e71 [flang] prevent undefined behavior in character MAXLOC folding
When folding MAXLOC/MINLOC, the current element being compared was moved twice
in row in case it became the new extremum. With numeric and logical types, it
made no difference (std::move is a no-op for them), but for characters
where the string storage is actually moved, it caused the new extremum to
be set to the empty string, leading to wrong results.

Note: I could have left the first std::move relating to logical Findloc, but it
brings nothing and makes the code less auditable, so I also removed it.

Jean Perier 5bc9ee1b78 [flang][lowering] Handle zero extent case in LBOUND
Follow up of https://reviews.llvm.org/D121488. Ensure lower bounds
are `1` when the related dimension extent is zero. Note that lower
bounds from descriptors are now guaranteed to fulfill this property
after the runtime/codegen patches.

Also fixes explicit shape array extent lowering when instantiating
variables to deal with negative extent cases (issue found while testing
LBOUND edge case). This notably caused allocation crashes when dealing
with automatic arrays with reversed bounds or negative size
specification expression. The standard specifies that the extent of such
arrays is zero. This change has some ripple effect in the current lit
tests.

Add move two helpers as part of this change:
- Add a helper to tell if a fir::ExtendedValue describes an assumed size
  array (last dimension extent is unknown to the compiler, both at compile
  time and runtime).

- Move and share getIntIfConstant from Character.cpp so that it can be
  used elsewhere (NFC).

Jean Perier 7f1adbaba9 [flang] Fix LBOUND rewrite on descriptor components
GetLowerBoundHelper rewrite in https://reviews.llvm.org/D121488 was
incorrect with POINTER/ALLOCATABLE components. The rewrite created a
descriptor inquiry to the component symbol only instead of the whole
named entity. The base information was lost, and not retrievable.
LBOUND(a(10)%p) became LBOUND(p).

Fix this regression, and also update DescriptorInquiry unparsing to
carry the kind information. DescriptorInquiries are KIND 8 expressions,
while LBOUND/SIZE/RANK, %LEN are default kind expressions.
This caused `print *,lbound(x,kind=8)` to unparse as `print*,lbound(x)` which is not
semantically the same (this unparsing issue was not an issue for
lowering, but I noticed it while writing my regression test).

[flang] Lower boxed procedure
In FIR, we want to wrap function pointers in a special box known as a
boxproc value. Fortran has a limited form of dynamic scoping
[https://tinyurl.com/2p8v2hw7] between "host procedures" and "internal
procedures". There are a number of implementations possible.

Boxproc typed values abstract away the implementation details of when a
function pointer can be passed directly (as a raw address) and when a
function pointer has to account for the presence of a dynamic scope.
When lowering Fortran syntax to FIR, all function pointers are emboxed
as boxproc values.

When creating LLVM IR, we must strip away the abstraction and produce
low-level LLVM "assembly" code. This patch implements that
transformation as converting the boxproc values to either raw function
pointers or executable trampolines on the stack as needed. The
trampoline then captures the dynamic scope context within an executable
thunk that can be passed instead of the function's raw address.

Some extra handling is required for Fortran functions that return a
character value to deal with LEN values here.

Some of the code in Bridge.cpp and ConvertExpr.cpp and be re-arranged to
faciliate the upstreaming effort.

This patch is part of the upstreaming effort from fir-dev branch.

Jean Perier 3ed899cc74 [flang] handle allocatable components when creating array temps
When creating an array temporary in the array copy pass, care must be
taken with allocatable components. The element components needs to be
given a clean unallocated status before being used in the assignments.
This is because assignment of allocatable components makes deep copy,
and may cause deallocation of the previous value if it was allocated.
Hence the previous allocation status cannot be let undefined.

On top of that, when cleaning-up the temp, all allocatable components
that may have been allocated must be deallocated.

This patch implements this by centralizing the code making and cleaning
array temps in ArrayValueCopy.cpp, and by calling Initialize and Destroy
runtime entry points when they are allocatable components.
