fa3abac8df 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.

60bf7320e2 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).

56a5573881 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).
