compile.c (compile_data_alloc): add padding when strict alignment
is required for memory access. Currently, the padding is enabled
only when the CPU is 32-bit SPARC and the compiler is GCC.
[Bug #9681] [ruby-core:61715]
compile.c (STRICT_ALIGNMENT): defined if strict alignment is required
compile.c (ALIGNMENT_SIZE, ALIGNMENT_SIZE_MASK, PADDING_SIZE_MAX):
new macros for alignemnt word size, bit mask, max size of padding.
compile.c (calc_padding): new function to calculate padding size.
