GCC 4.4.0 gives an error on the "int" declaration for example saying that it has already been declared (using the "short" one). Using templates here allow the compiler to distinguish between the function to choose. Also, "llvm/Support/DataTypes.h" was not included, leading to error messages about not knowing "uint32_t" for example. Patch by Samuel Tardieu. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57292 91177308-0d34-0410-b5e6-96231b3b80d8
