Nicholas Piggin 8cfe6d241b target/ppc: Sign-extend large decrementer to 64-bits 
When storing a large decrementer value with the most significant
implemented bit set, it is to be treated as a negative and sign
extended.

This isn't hit for book3s DEC because of another bug, fixing it
in the next patch exposes this one and can cause additional
problems, so fix this first. It can be hit with HDECR and other
edge triggered types.
