  [CIR] Change default assumption about allowing builtins (#144004)

The code to read the "nobuiltins" attributes hasn't been implemented
yet, but we were defaulting to the assumption that use of builtins is
allowed for function calls that we recognize as standard C library calls
and have builtin equivalents of. This change reverses that assumption so
that when such calls are encountered, we just emit the call. This is a
better default assumption, and since our builtin handling for these
functions isn't implemented yet, it also allows us to compile more
programs.
