Following the example set by commit 58a359e585, we can squeeze out
a little more performance from COPY FROM (FORMAT {text,csv}) by
inlining CopyReadLineText() and passing the is_csv parameter as a
constant. This allows the compiler to emit specialized code with
fewer branches.
This is preparatory work for a proposed follow-up commit that would
further optimize this code with SIMD instructions.
