* score/cpu/i386/rtems/score/cpu.h:
Added #ifdef ASM constructs so that this header can be
included from assembly code.
Increased CPU_STACK_ALIGNMENT to 16 bytes. Gcc maintains
16-byte alignment and it may be a advantageous to provide
initial 16-byte alignment. When using SSE some gcc versions
may produce code that crashes if the stack is not 16-byte aligned.
Make sure _CPU_Context_Initialize() sets the thread stack
up so that it is aligned to CPU_CACHE_ALIGNMENT.
* score/cpu/i386/cpu_asm.S:
Align stack to CPU_CACHE_ALIGNMENT before calling C-code.
