[Bug target/39558] Bad interaction of decls named 'vector' and -maltivec vector support

Ah, I see.  The problem is that rs6000_macro_to_expand sometimes calls
cpp_get_token (when seeing a macro after vector token), and removes optionally
some CPP_PADDING tokens and a NT_MACRO token (with PREV_WHITE set on it).
This only affects vector, not pixel nor bool.  Unfortunately, we can't
expand vector to a macro defined as 'vector ' (without quotes), because that
would mean infinite recursion.  We could perhaps if macro_to_expand hook
returns NULL set PREV_WHITE on the next token (on the libcpp side, as
rs6000_macro_to_expand sees tokens as const cpp_token), or insert a CPP_PADDING
token.
