[Bug sim/11965] New: vmhaddshs, vmhraddshs uninitialized variable may cause wrong VSCR result

["hp at sourceware dot org" <sourceware-bugzilla at sourceware dot org>]

Looking at sim/ppc/altivec.igen 1.4 it seems the sat variable for vmhaddshs and
vmhraddshs isn't initialized before being "|=" in the vector element loop, so
depending on what the host and compiler makes of it, VSCR (from calling
ALTIVEC_SET_SAT) may be set incorrectly.  I guess not many codes looks at it,
hence going undetected until now.  Just a random observation, no test-case or
anything.  Not even sure I see right. :)
