In merge FSOURCE and TSOURCE must have the same Fortran dynamic types,
but this does not imply that FSOURCE and TSOURCE will be lowered to the
same MLIR types. For instance, TSOURCE may be a character expression
with a compile type constant length (!fir.char<1,4>) while FSOURCE may
have dynamic length (!fir.char<1,?>).
Cast FSOURCE to TSOURCE MLIR types to handle these cases.
This patch is part of the upstreaming effort from fir-dev branch.

This patch adds support for lowering of the `merge` intrinsics from
Fortran to the FIR dialect of MLIR.
This is part of the upstreaming effort from the `fir-dev` branch in [1].
