vec_ceil and friends are expanded by vecintrin.h to __builtin_s390_vfi
which is an overloaded builtin being replaced by either
__builtin_s390_vfisb or __builtin_s390_vfidb depending on its argument
types.
The problem in this PR was that the overloaded builtin definition of
__builtin_s390_vfi was missing in s390-builtins.def.

Consolidate all symbol name handling into the new file names.cc. This
is intended to define all the names that will appear in the generated
assembly code. Names that will not appear in the assembly code, such
as local variable names or label names, remain where they are.
This consolidation is not intended to change any of the existing
symbol names. Tested by building without and without this patch and
comparing the libgo symbol table.
