-Squashed version of several commits to fix the tracelogger.
-
-Taken from
-https://github.com/GNOME/jhbuild/blob/master/patches/mozjs38-fix-tracelogger.patch.
-
-# === Fix the SM38 tracelogger ===
-# This patch is a squashed version of several patches that were adapted
-# to fix failing hunks.
-#
-# Applied in the following order, they are:
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1223767
-#    Assertion failure: i < size_, at js/src/vm/TraceLoggingTypes.h:210 
-#    Also fix stop-information to make reduce.py work correctly.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1227914
-#    Limit the memory tracelogger can take.
-#    This causes tracelogger to flush data to the disk regularly and prevents out of 
-#    memory issues if a lot of data gets logged.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1155618
-#    Fix tracelogger destructor that touches possibly uninitialised hash table.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1223636
-#    Don't treat extraTextId as containing only extra ids.
-#    This fixes an assertion failure: id == nextTextId at js/src/vm/TraceLoggingGraph.cpp
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1227028
-#    Fix when to keep the payload of a TraceLogger event.
-#    This fixes an assertion failure: textId < uint32_t(1 << 31) at js/src/vm/TraceLoggingGraph.h
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1266649
-#    Handle failing to add to pointermap gracefully.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1280648
-#    Don't cache based on pointers to movable GC things.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1224123
-#    Fix the use of LastEntryId in tracelogger.h.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1231170
-#    Use size in debugger instead of the current id to track last logged item.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1221844
-#    Move TraceLogger_Invalidation to LOG_ITEM.
-#    Add some debug checks to logTimestamp.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1255766
-#    Also mark resizing of memory.
-# * https://bugzilla.mozilla.org/show_bug.cgi?id=1259403
-#    Only increase capacity by multiples of 2.
-#    Always make sure there are 3 free slots for events.
