As reported in https://reviews.llvm.org/D91383#2401825, this
assert breaks external -aa-eval tests. We'll have to fix this
case before re-enabling it.

If the containing allocator build uses -DGWP_ASAN_DEFAULT_ENABLED=false
then the option will default to false.  For e.g. Scudo, this is simpler
and more efficient than using -DSCUDO_DEFAULT_OPTIONS=... to set gwp-asan
options that have to be parsed from the string at startup.

Adds support for setting the `Rule` field. In the process, refactors the code that accesses that field and adds a constructor that doesn't require a rule argument.

This feature is needed by checks that must set the rule *after* the check class
is constructed. For example, any check that maintains state to be accessed from
the rule needs this support. Since the object's fields are not initialized when
the superclass constructor is called, they can't be (safely) captured by a rule
passed to the existing constructor.  This patch allows constructing the check
superclass fully before setting the rule.

As a driveby fix, removed the "optional" from the rule, since rules are just a
set of cases, so empty rules are evident.

We have workarounds for two different cases where vccz can get out of
sync with the value in vcc. This fixes them in two ways:

1. Fix the case where the def of vcc was in a previous basic block, by
pessimistically assuming that vccz might be incorrect at a basic block
boundary.

2. Fix the handling of pre-existing waitcnt instructions by calling
generateWaitcntInstBefore before examining ScoreBrackets to determine
whether there's an outstanding smem read operation.

[Reassociate] Don't convert add-like-or's into add's if they appear to be part of load-combining idiom

As Wei Mi is reporting in post-commit review
  https://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20201116/853479.html
teaching -reassociate about add-like-or's (70472f34) results in breaking apart
load widening patterns, and reassociating them.

For now, simply exclude any such `or` that appears to be a root of
load widening idiom from the or->add transformation.

Note that the heuristic is greedy, it doesn't ensure that loads
can *actually* be widened into a single load.

While that's great, it prevents the actual load widening in backend,
and that is not good. We should have load widening in middle-end,
but for now we should at least not regress the naive patterns..

I noticed that Process is inheriting from UserID to store its PID value. This patch
replaces this with a dedicated field in the Process class. This is NFC, but has some
small effects on the code using Process:
* `GetID()` now returns a `lldb::pid_t` like all other process code instead of `lldb::user_id_t`. Both are typedefs for `uint64_t`, so no change in behaviour.
* The equality operators defined for UserID no longer accept Process instances.
* Removes the inherited method `Process::Clear()` which didn't actually clear anything beside the PID value.

We maybe should also remove the getters/setters to `S/GetPID` or something like that. I can update all the code for that
in a follow-up NFC commit.
