c3477c51e5 [flang] Add CHARACTER type lowering helpers and runtime. 
In order for these files to build properly, this patch rolls up a number of changes that have been made to various files that have been upstreamed.

Implementations for the interfaces included in Bridge.h and IntrinsicCall.h will be included in a future diff.

b938eaec55 [flang] Add BoxValue.h 
The bridge uses internal boxes of related ssa-values to track all the
information associated with a Fortran variable. Variables may have a
location and a value, but may also carry other properties such as rank,
shape, LEN parameters, etc. in Fortran.

b5d51c2448 [flang] Add SymbolMap 
The symbol map is a data structure for tracking variables in a subprogram during the lowering of that subprogram to FIR/MLIR. These data structures will be used by the bridge, which has not been upstreamed yet.
