[PowerPC] Truncate exponent parameter for vec_cts,vec_ctf
On PowerPC, the vec_ct* builtin function take the form of eg. d=vec_cts(a,b)
LLVM (llc) will crash when a user specifies a number out of the allowed range
(0-31) for b.This patch truncates b so that we avoid the backend crash in some cases.
Further documentation for the builtins can be found here:
