Patch to compress line info
This patch removes column information from LTO (so we lose carret diagnostics
in warnings/errors output at LTO time that seems resonable thing to do) and
avoid entering duplicate locators into the linemap. The patch reduces linemap
usage from 23% to 5% of GGC memory saving 1-2GB on Mozilla. (also reducing LTO
file size).
