[ORC][C-bindings] Fix some ORC C bindings function names and signatures.

LLVMOrcDisposeObjectLayer and LLVMOrcExecutionSessionGetJITDylibByName did not have matching signatures between the C-API header and binding implementations. Fixes http://llvm.org/PR49745. Patch by Mats Larsen. Thanks Mats! Reviewed by: lhames Differential Revision: https://reviews.llvm.org/D99478 (cherry picked from commit 666df2e)
