The CLANG38 toolchain aligns 64-bit data types on an 4-Byte boundary for IA32, which is the default for the GNU ABI. For the Microsoft ABI used by UEFI however, natural alignment holds for all data types on all architectures. Add the "-malign-double" flag already used by the GCC toolchains to ensure 64-bit data types are aligned on an 8-Byte boundary instead.
