S/390: Fix vector all/any cc modes.
This fixes a problem with the vector compares producing CC mode
results.
The instructions produce condition code modes which can be either
interpreted to check an ALL elements or an ANY element result. As the
modes where used before they could not be inverted by the middle-end
by inverting the comparison code (e.g. eq to ne). The result usually
was just wrong.
In fact inverting a comparison code on an CCVALL mode would require to
also change the mode to CCVANY but this cannot be done easily in the
middle-end. With this patch the meaning of an ALL cc mode only refers
to the not-inverted comparison code (e.g. eq, gt, ge). With that
change inverting the comparison code matches a not operation on the
condition code mask again.
Bootstrapped and regression tested on s390 and s390x.

compiler: add slice initializers to the GC root list
As of https://golang.org/cl/32917 we can put slice initializers in the
.data section. The program can still change the values in those
slices. That means that if the slice elements can contain pointers,
we need to register the entire initializer as a GC root.
This would be straightforward except that we only have a Bexpression
for the slice initializer, not an Expression. So introduce a
Backend_expression type that wraps a Bexpression as an Expression.
