This patch provides a workaround for the ASM_ASSERT label issue and also reworks the use of labels in assembly macros. If the caller of the ASM_ASSERT macro happened to use the label '1' to jump past the ASM_ASSERT macro, it would not have worked since the ASM_ASSERT macro internally used the same label. Hence, as a workaround, this patch makes the label a high number in the expectation that the caller will never use it. Also updated the other assembly macros using numerical labels to named lables.
