Hi all:

This patch update `Bit operations` section in libgcc.text, most bit
operation function is take an unsigned integer instead of signed
integer in libgcc/libgcc2.c [1], and it seem more make sense :)

Although Kito has signed FSF agreement, he has not got his
read-write svn access yet.

So I can help to commit this patch for him.
Committed as Rev.218559:
