Add test case: steptest now runs with the arena clamped, and checks that mps_arena_step does not unclamp it.

Always recording events into buffers, but only writing them to the telemetry stream if they're enabled.

Abolishing event formats. Each event now has its own structure.
Event parameters are now written directly into the event buffer, rather than being copied twice.

Separated XCI3GC (gcc) from XCI3LL (clang) platforms, so that we can build both 32- and 64-bit binaries with clang.

ArenaPoll will still call TracePoll if clamped...
but TracePoll won't start a new trace if clamped
ArenaStep won't start an opportunistic full collect if clamped
ArenaStep won't advance pollThreshold, ever
traceFlip asserts that clamped is FALSE.
(see http://info.ravenbrook.com/mail/2010/02/23/13-19-24/0.txt)

But no, clamped is more complex than that.
- Certain mps.h calls affect it.
- Certain MPS tests use it for more control and reproducibility.
- MPS itself uses it, as part of starting a full collect, for which it must first run any current trace to completion without starting any new ones.
In particular, this set of changes asserts:
MPS ASSERTION FAILURE: ArenaGlobals(arena)->clamped == FALSE
trace.c
534
because mps_arena_collect() tries to start a full collect while clamped.

So this changelist is for historical interest only, and will be backed out.

Changes:
- separate ArenaPoll and ArenaStep code paths;
- simplify ArenaPoll;
- loop calling TracePoll to catch-up;
zcoll: 100MB is a more sensible arena size than 0.5 MB
Warning: barely "experimental" code quality, omitting the following necessities:
- consideration of interactions with ArenaStep,
- re-engineering of ArenaPoll and friends.

poolamc.c tidy up:
neater implementation of obj1pip (amcReclaimNailed)
neater implementation of amcResetTraceIdStats -- no need for a function any more
delete lots of obsolete temporary diagnostic (superseded by AMCTraceEnd_pageret)
a few more avers (especially on buffer empty)
also revert temporary diagnostic changes in arena.c, config.h, diag.c, global.c
diag.c: fix diag-buffer at 100 screenfuls (200000 chars).
zcoll.c: reinstate Make 50000 with occasional big objs.

re-create them immediately after a trace sends its last message.
Store them, one per TraceId, in ArenaStruct. Cope correctly if they
cannot be created (ControlAlloc fails). Destroy them correctly on
mps_arena_destroy. See job001989 and design/message-gc#lifecycle
(not yet written).
