Takuya Shimizu 72f6abb9bc [clang][Sema] Fix format size estimator's handling of %o, %x, %X with alternative form ...

The wrong handling of %x specifier with alternative form causes a false positive in linux kernel (https://github.com/ClangBuiltLinux/linux/issues/1923#issuecomment-1696075886)

The kernel code: 651a00bc56/drivers/media/pci/cx18/cx18-mailbox.c (L99)

This patch fixes this handling, and also adds some standard wordings as comments to clarify the reason.
