Patch 2/3 of the transition step 1 described in
https://discourse.llvm.org/t/rfc-enabling-the-hlfir-lowering-by-default/72778/7.
All the modified tests are still here since coverage for the direct
lowering to FIR was still needed while it was default. Some already have
an HLFIR version, some have not and will need to be ported in step 2
described in the RFC.
Note that another 147 lit tests use -emit-fir/-emit-llvm outputs but do
not need a flag since the HLFIR/no HLFIR output is the same for what is
being tested.
Handles function with character return.
Character scalar results are passed as arguments in lowering so
that an assumed length character function callee can access the result
length.
This patch is part of the upstreaming effort from fir-dev branch.

This patch allows the lowring of simple empty function with a
scalar integer or logical return value.
The code in ConvertType.cpp is cleaned up as well. This file was landed
together with the initial flang push and lowering was still a prototype
at that time. Some more cleaning will come with follow up patches.
