When an explicit pointee type is provided it must be equal to the pointer element type, so this will have to wait until migration to opaque pointers is complete:

Prepare struct_gep for opaque pointers
838042a 
Imlement struct_gep using LLVMBuildStructGEP2 which takes an explicit
type argument instead of deriving it from a pointer type.
@tmiasko
Prepare gep for opaque pointers
4013e09 
Implement gep using LLVMBuildGEP2 which takes an explicit type argument
instead of deriving it from a pointer type.
@tmiasko
Prepare inbounds_gep for opaque pointers
77e5e17 
Implement inbounds_gep using LLVMBuildInBoundsGEP2 which takes an
explicit type argument instead of deriving it from a pointer type.
@tmiasko
Replace LLVMConstInBoundsGEP with LLVMConstInBoundsGEP2*
8e0df32 
A custom reimplementation of LLVMConstInBoundsGEP2 is used, since the
LLVM contains a declaration of LLVMConstInBoundsGEP2 but not the
implementation.
