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.

Allow fir.rebox input and output element type to differ for characters
if:
- Any of the character type is dynamic. Fortran allows making pointer
assignments between deferred and constant lengths entities, making this
case useful (if the input length is dynamic and the output length constant,
it is a user requirement that the length matches at runtime. There is no
option to check this at runtime, but it could be added as an option to
fir.rebox codegen later if desired).
- Or, there is a slice in the fir.rebox (the fir.rebox can implement a
substring view, hence the constant output and input lengths).
This is only a verifier constraint change, the fir.rebox codegen is not
impacted and already support those cases.
Add related FIR parsing, error, and codegen tests.

This patch adds support for:
* `-S` in Flang's compiler and frontend drivers,
and implements:
* `-emit-obj` in Flang's frontend driver and `-c` in Flang's compiler
driver (this is consistent with Clang).
(these options were already available before, but only as placeholders).
The semantics of these options in Clang and Flang are identical.
The `EmitObjAction` frontend action is renamed as `BackendAction`. This
new name more accurately reflects the fact that this action will
primarily run the code-gen/backend pipeline in LLVM. It also makes more
sense as an action implementing both `-emit-obj` and `-S` (originally,
it was just `-emit-obj`).
`tripleName` from FirContext.cpp is deleted and, when a target triple is
required, `mlir::LLVM::LLVMDialect::getTargetTripleAttrName()` is used
instead. In practice, this means that `fir.triple` is replaced with
`llvm.target_triple`. The former was effectively ignored. The latter is
used when lowering from the LLVM dialect in MLIR to LLVM IR (i.e. it's
embedded in the generated LLVM IR module). The driver can then re-use
it when configuring the backend. With this change, the LLVM IR files
generated by e.g. `tco` will from now on contain the correct target
triple.
The code-gen.f90 test is replaced with code-gen-x86.f90 and
code-gen-aarch64.f90. With 2 seperate files we can verify that
`--target` is correctly taken into account. LIT configuration is updated
to enable e.g.:
```
! REQUIRES: aarch64-registered-target
```

Currently, CGOps.h and FIROps.h contain `using namespace mlir;`. Every
file that includes one of these header files (directly and transitively)
will have the MLIR namespace enabled. With name-clashes within
sub-projects (LLVM and MLIR, MLIR and Flang), this is not desired. Also,
it is not possible to "un-use" a namespace once it is "used". Instead,
we should try to limit `using namespace` to implementation files (i.e.
*.cpp).
This patch removes `using namespace mlir;` from header files and adjusts
other files accordingly. In header and TableGen files, extra namespace
qualifier is added when referring to symbols defined in MLIR. Similar
approach is adopted in source files that didn't require many changes. In
files that would require a lot of changes, `using namespace mlir;` is
added instead.

The front-end and the runtime are currently using the unix logical
representation, but lowering was not. These inconsistencies could
caused issues.
The only place that defines what the logical representation is in
lowering is the translation from FIR to LLVM (FIR is agnostic to the
actual representation). More precisely, the LLVM implementation of
`fir.convert` between `i1` and `fir.logcial` is what defines the
representation:
- `fir.convert` from `i1` to `fir.logical` defines the `.true.` and `.false.`
canonical representations
- `fir.convert` from `fir.logical` to `i1` decides what the test for
truth is.
Unix representation is:
- .true. canonical integer representation is 1
- .false. canonical integer representation is 0
- the test for truth is "integer representation != 0"
For the record, the previous representation that was used was in
codegen was:
- .true. canonical integer representation is -1 (all bits 1)
- .false. canonical integer representation is 0
- the test for truth is "integer representation lowest bit == 1"

This change updates the mapping of derived types and type descriptor
object names to support kind parametrized derived types (PDT).
It moves the custom name mapping to the internal name utility.
To improve robustness and error reporting, type descriptors are also now
required to be generated in all compilation unit that manipulates
derived types. The previous codegen relied on the fact that descriptors
not defined in the current FIR module were available externally. Errors
with missing type descriptors were only caught at link time.
This patch makes derived type definition mandatory, except if the
derived types are expected to not have derived type descriptors (builtin
types), or if the newly added debug switch `--ignore-missing-type-desc`
is set. In those cases, a null pointer is used as type descriptor
pointer. The debug switch intends to help testing FIR to LLVM passes
without having to bother providing type descriptor data structures that
are normally built by the front-end.

The Func has a large number of legacy dependencies carried over from the old
Standard dialect, which was pervasive and contained a large number of varied
operations. With the split of the standard dialect and its demise, a lot of lingering
dead dependencies have survived to the Func dialect. This commit removes a
large majority of then, greatly reducing the dependence surface area of the
Func dialect.
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:
* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

Currently, code generation was creating weak symbols for derived type
descriptor global it could not find in the current compilation unit.
The rational is that:
- the derived type descriptors of external module derived types are
generated in the compilation unit that compiled the module so that
the type descriptor address is uniquely associated with the type.
- some types do not have derived type descriptors: the builtin derived
types used to create derived type descriptors. The runtime knows
about them and does not need them to accomplish the feat of
describing themselves. Hence, all unresolved derived type descriptors
in codegen cannot be assumed to be resolved at link time.
However, this caused immense debugging pain when, for some reasons, derived
type descriptor that should be generated were not. This caused random
runtime failures instead of a much cleaner link time failure.
Improve this situation by allowing codegen to detect the builtin derived
types that have no derived type descriptors and requiring the other
unresolved derived type descriptor to be resolved at link time.
Also make derived type descriptor constant data since this was a TODO
and makes the situation even cleaner. This requiring telling lowering
which compiler created symbols can be placed in read only memory. I
considered using PARAMETER, but I have mixed feeling using it since that
would cause the initializer expressions of derived type descriptor to
be invalid from a Fortran point of view since pointer targets cannot be
parameters. I do not want to start misusing Fortran attributes, even if
I think it is quite unlikely semantics would currently complain. I also
do not want to rely on the fact that all object symbols with the
CompilerCreated flags are currently constant data. This could easily
change in the future and cause runtime bugs if lowering rely on this
while the assumption is not loud and clear in semantics.
Instead, add a ReadOnly symbol flag to tell lowering that a compiler
generated symbol can be placed in read only memory.
