[PATCH] rs6000: Fix misnamed built-in

[Bill Schmidt via Gcc-patches]

The description in rs6000-builtin.def provides for a builtin named
__builtin_altivec_xst_len_r.  However, it is hand-defined in
altivec_init_builtins as __builtin_xst_len_r, against the usual naming
practice.  Fix that.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no
regressions; committed as obvious.
