[flang] Try to lower math intrinsics to math operations first.
This commit changes how math intrinsics are lowered: we, first,
try to lower them into MLIR operations or libm calls via
mathOperations table and only then fallback to pgmath runtime calls.
The pgmath fallback is needed, because mathOperations does not
support all intrinsics that pgmath supports. The main purpose
of this change is to get rid of llvmIntrinsics table so that
we do not have to update both llvmIntrinsics and mathOperations
when adding new intrinsic support.
mathOperations lowering should phase out pgmath lowering, when
more operations are available (e.g. power operations being
added in D129809 and D129811; complex type operations from
Complex dialect).

[flang] Lower Fortran math intrinsic operations into MLIR ops or libm calls.
Added new -lower-math-early option that defaults to 'true' that matches
the current math lowering scheme. If set to 'false', the intrinsic math
operations will be lowered to MLIR operations, which should potentially
enable more MLIR optimizations, or libm calls, if there is no corresponding
MLIR operation exists or if "precise" mode is requested.
The generated math MLIR operations are then converted to LLVM dialect
during codegen phase.
The -lower-math-early option is not exposed to users currently. I plan to
get rid of the "early" lowering completely, when "late" lowering
is robust enough to support all math intrinsics that are currently
supported via pgmath. So "late" mode will become default and -lower-math-early
option will not be needed. This will effectively eliminate the mandatory
dependency on pgmath in Fortran lowering, but this is WIP.
