[LLVM-C] Miscellaneous Cleanups in DIBuilder Bindings

[CodaFi]

Summary

• rL328953 does not include bindings for LLVMDIBuilderCreateClassType and LLVMDIBuilderCreateBitFieldMemberType despite declaring their prototypes. Provide these bindings now.
• Switch to more precise types with specific numeric limits matching the DIBuilder's C++ API.

[whitequark]

Did these ever appear in a release? They change ABI, so if yes, this needs renaming every function to a *2 variant.

[CodaFi]

Unless there has been a release since 6.0(.1), we should be free to change these. We merged the referenced patch after that.
