Checks to see if there is a symbol in the otherProgram that conflicts
with the indicated symbol. A conflict can be one of these types:
1) a symbol other than label or function that has the same name and 
namespace as another non label or function.
2) a symbol at the same address with the same name and namespace.

@param program the program that contains the specified symbol
@param symbol the symbol (Can be original, latest, or my.)
@param otherProgram the program to be checked for a conflicting symbol
@param saveConflict if true this will also save the conflict for processing or in
some cases automatically process the conflict.
@return true if there is a symbol name conflict
