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.

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 (70472f3) 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..

Would be nice to have constant expression evaluator support general template
value-dependent expressions, but it requires more work.
This patch is a good start I think, to handle the error-only
value-dependent expressions.

This patch generalizes the extraction of a constraint for a given
condition. It allows decompose to return a vector of c * X pairs, which
allows de-composing multiple instructions in the future.
It also adds more clarifying comments.
The SystemZISD::IABS node is no longer needed since ISD::ABS can be used
instead.

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.

Matrix types in memory are represented as arrays, but accessed through
vector pointers, with the alignment specified on the access operation.
For inline assembly, update pointer arguments to use vector pointers.
Otherwise there will be a mis-match if the matrix is also an
input-argument which is represented as vector.

The side effect infrastructure is based on the Effect and Resource class
templates, instances of instantiations of which are constructed as
thread-local singletons. With this scheme, it is impossible to further
parameterize either of those, or the EffectInstance class that contains
pointers to an Effect and Resource instances. Such a parameterization is
necessary to express more detailed side effects, e.g. those of a loop or
a function call with affine operations inside where it is possible to
precisely specify the slices of accessed buffers.
Include an additional Attribute to EffectInstance class for further
parameterization. This allows to leverage the dialect-specific
registration and uniquing capabilities of the attribute infrastructure
without requiring Effect or Resource instantiations to be attached to a
dialect themselves.
Split out the generic part of the side effect Tablegen classes into a
separate file to avoid generating built-in MemoryEffect interfaces when
processing any .td file that includes SideEffectInterfaceBase.td.
