Fix ARM ABI issues for RenderScript.

Bug: http://b/26987366

Although I did upstream a working patch for our ARM ABI vector problems,
the patch is insufficient for RenderScript, as it is *NOT* an Android
target. It is a generic Linux target, so we need to also check our
LanguageOptions to see if we should use the alternate vector ABI.
