Adhemerval Zanella 1c7d69bbe2 PR12716: PPC crashes on vector compare
Vector compare using altivec 'vcmpxxx' instructions have as third argument
a vector register instead of CR one, different from integer and float-point
compares. This leads to a failure in code generation, where 'SelectSETCC'
expects a DAG with a CR register and gets vector register instead.

This patch changes the behavior by just returning a DAG with the 
vector compare instruction based on the type. The patch also adds a testcase
for all vector types llvm defines.

It also included a fix on signed 5-bits predicates printing, where
signed values were not handled correctly as signed (char are unsigned by
default for PowerPC). This generates 'vspltisw' (vector splat)
instruction with SIM out of range.
