[flang][NFC] Move TypeConverter.h header file to include dir
After the extraction of the TypeConverter, move the header files
to the include dir so the shared library build is fine.

ba0c082b49 [flang] Use the newly introduced AliasAnalysisOpInterface.
This revision uses the AliasAnalysisOpInterface introduced in
https://reviews.llvm.org/D144851 to set the tbaa attributes
of load and store ops. With the attribute it is also possible to
set the attribute on atomics as well as on memcopy and
memove intrinsics as soon as https://reviews.llvm.org/D144965
lands.

fef08da4b7 [mlir][llvm] Store memory op metadata using op attributes.
The revision introduces operation attributes to store tbaa metadata on
load and store operations rather than relying using dialect attributes.
At the same time, the change also ensures the provided getters and
setters instead are used instead of a string based lookup. The latter
is done for the tbaa, access groups, and alias scope attributes.

The goal of this change is to ensure the metadata attributes are only
placed on operations that have the corresponding operation attributes.
This is imported since only these operations later on translate these
attributes to LLVM IR. Dialect attributes placed on other operations
are lost during the translation.

9c84d20fa6 [flang] Generate TBAA information.
This is initial version of TBAA information generation for Flang
generated IR. The desired behavior is that TBAA type descriptors
are generated for FIR types during FIR to LLVM types conversion,
and then TBAA access tags are attached to memory accessing operations
when they are converted to LLVM IR dialect.

In the initial version the type conversion is not producing
TBAA type descriptors, and all memory accesses are just partitioned
into two sets of box and non-box accesses, which can never alias.

The TBAA generation is enabled by default at >O0 optimization levels.
TBAA generation may also be enabled via `apply-tbaa` option of
`fir-to-llvm-ir` conversion pass. `-mllvm -disable-tbaa` engineering
option allows disabling TBAA generation to override Flang's default
(e.g. when -O1 is used).

SPEC CPU2006/437.leslie3d speeds up by more than 2x on Icelake.
