compiler: share LLVM function type construction

Browse Source 
getFunction and getLLVMFunctionType duplicate the construction of LLVM
result types for functions with zero, one, or multiple results.

Move this code to getLLVMResultType. Also split the existing parameter
expansion code into expandDirectFormalParamType so callers can request
the current flattened parameter types directly.
