Fix intrinsics.alloca code generation

Browse Source 
There was a disconnect between the declared return type for alloca
intrinsic in check_builtin.cpp (multi_pointer(t_u8)) and the generated
result type in llvm_backend_proc.cpp (t_u8_ptr).

This allowed slicing the return type, but in the code generation process
the type of the expression wasn't sliceable, which triggered the assert.

Fixes #2139
