1ec8c4a141 Improve handling of telemetry events on the critical path: 
1. Being on the critical path is a property of the code location where the event is emitted, not of the event type, so indicate this using EVENT_CRITICAL macros rather than a field in the event table.
2. Compile out events on the critical path in hot varieties.
3. Remove TraceFixWhite event (redundant with TraceFixSeg).
4. No need for special handling of PoolFree event -- this are already skipped in hot varieties by dispatching directly to the pool class via PoolFreeMacro.

cbf9885146 Document the event parameters. 
Split event ArenaAccess into ArenaAccessBegin and ArenaAccessEnd to avoid the need for the count field.
New events SegReclaim and SegScan.
Delete some redundant events: AMCFinish (PoolFinish), AMCFix, AMCFixForward, AMCFixInPlace (TraceFix), AMCGenCreate (GenInit), AMCGenDestroy (GenFinish), AMCInit (PoolInitAMC), AMCReclaim (SegReclaim), AMCScanBegin, AMCScanEnd (SegScan), ArenaWriteFaults (ArenaAccessBegin), PoolInitMV, TraceScanSeg (SegScan).
Add result code field to events ArenaAllocFail, CommitLimitSet, SegAllocFail.
Remove arena field from events PoolInitAMS, PoolInitMFS, PoolInitMVFF (already appeared in generic PoolInit event).

77506b67e7 There's no point keeping the definitions of old events, especially since we have changed the event format. name events consistently with initial capital letters and put them in alphabetical order.

882d86bac1 Remove call to pause_end from tracedestroy; see <https://info.ravenbrook.com/mail/2018/10/12/10-20-07/0/> 
The MPS passes the number of system pools to the monitor via the ArenaCreate events, to avoid the monitor having to know how many this is.

94e3f8895b Update xcode project for xcode 10.0. 
Xcode 10.0 no longer supports building for IA-32, so the MPS can no longer support building for xci3ll using Xcode.
Revise example Scheme interpreter so that it can be compiled even if getopt.h includes unistd.h (as it does on macOS).
