Nicholas Piggin 411b38fe68 powerpc/64s: fix program check interrupt emergency stack path 
[ Upstream commit 3e607dc4df180b72a38e75030cb0f94d12808712 ]

Emergency stack path was jumping into a 3: label inside the
__GEN_COMMON_BODY macro for the normal path after it had finished,
rather than jumping over it. By a small miracle this is the correct
place to build up a new interrupt frame with the existing stack
pointer, so things basically worked okay with an added weird looking
700 trap frame on top (which had the wrong ->nip so it didn't decode
bug messages either).

Fix this by avoiding using numeric labels when jumping over non-trivial
macros.
