Reason for revert: Fragmentation of LABs could result in increasing memory usage (pages) instead of shrinking. BUG=chromium:620320 LOG=N Original issue's description: > [heap] Add page evacuation mode for new->new > > Adds an evacuation mode that allows moving pages within new space without > copying objects. > > Basic idea: > a) Move page within new space > b) Sweep page to make iterable and process ArrayBuffers > c) Finish sweep till next scavenge > > Threshold is currently 70% live bytes, i.e., the same threshold we use > to determine fragmented pages. > > BUG=chromium:581412 > LOG=N > CQ_EXTRA_TRYBOTS=tryserver.v8:v8_linux_arm64_gc_stress_dbg,v8_linux_gc_stress_dbg,v8_mac_gc_stress_dbg,v8_linux64_tsan_rel,v8_mac64_asan_rel > > Committed: https://crrev.com/49b23201671b25092a3c22eb85783f39b95a5f87 > Cr-Commit-Position: refs/heads/master@{#36990} TBR=ulan@chromium.org # Not skipping CQ checks because original CL landed more than 1 days ago.
