Hello, Everyone.
Now some codegens by default emit zero-initialized data to .bss section.
However, sometimes it's really necessary not to do so. This patch will
add handling of "-fno-zero-initialized-in-bss" llvm-gcc' option. It's
necessary to compile crt*.o properly.
PS: Also some fix some small typo. :)
