The following makes sure that using TYPE_PRECISION on VECTOR_TYPE
ICEs when tree checking is enabled. This should avoid wrong-code
in cases like PR110182 and instead ICE.
Bootstrap and regtest pending on x86_64-unknown-linux-gnu, I guess
there will be some fallout of such change ...
* tree.h (TYPE_PRECISION): Check for non-VECTOR_TYPE.
