BaseTools: Fix IA32 UINT64 alignment for CLANG toolchains

Currently, UINT64 is not 8-byte aligned for CLANG* toolchains on IA32,
which causes ABI differences between IA32 and X64 in such simple examples as:

struct S {UINT32 A; UINT64 B;};

Pass -malign-double to align it to 8 bytes, as is done for GCC already.
