Adjust loops in preperation for FX_STRSIZE int->size_t
Adjust loop conditions and behaviours in preperation for convering the underlying type of FX_STRSIZE to size_t. These changes are not dependent on the type switch occuring, so can be landed before hand. BUG=pdfium:828 Change-Id: I5f950c99c10e5ef0836959e3b1dd2e09f8f5afc0 Reviewed-on: https://pdfium-review.googlesource.com/12750 Commit-Queue: Ryan Harrison <rharrison@chromium.org> Reviewed-by: Henrique Nakashima <hnakashima@chromium.org>
