This ensures that functions in included files have the correct path
in their file metadata.
Note: This patch also sets all locations to have the full path names.

Previously, the DISubroutineType attribute used an optional result
parameter and an optional argument types array to model the subroutine
signature. LLVM IR debug metadata, on the other hand, has one types
list whose first entry maps to the result type. That entry may be
null to model a void result type. The type list may also be entirely
empty not specifying any type information. The latter is problematic
since the current DISubroutineType attribute cannot express it.
The revision changes DISubroutineTypeAttr to closely follow the
LLVM metadata design. In particular, it uses a single types parameter
array to model the subroutine signature and introduces an explicit
DIVoidResultTypeAttr to model the null entries.

This reverts commit 81f57b6
and relands commit a960547
Fixes flang build and drop_begin on an empty array ref.
Recent changes to MLIR meant that Flang does not generate any debug line
table information.
This patch adds a pass that provides some foundation work with which
basic line table debug info can be generated. A walk is performed on
all the `func` ops in the module and they are decorated with a fusedLoc
op that contains the debug metadata for the subroutine along with
location information.
Alternatives include populating this info during lowering or during FIR
to LLVM Dialect conversion.
Note: Patches in future will add
-> more realistic debug info for types and other fields.
-> driver flags to control generation of debug.
Fixes#58634.
