[MLIR] Clarify (test-scf-)parallel-loop-collapsing
1. parallel-loop-collapsing is renamed to test-scf-parallel-loop-collapsing.
2. The pass adds various checks to provide error messages instead of
hitting assert failures.
3. Testing is added to verify these error messages
This is roughly an NFC. The name changes, but all checked behavior
previously would have resulted in an assertion failure. Almost no new
support is added, so this pass is still limited in scope to testing the
transform behaves correctly with input arguments that perfectly match
the ParallelLoop's iterator arg set. The one new piece of functionality
is that invalid operations will now be skipped with an error messages
instead of producing an assertion failure, so the pass can be used with
expected failures for pieces of the IR not cared about with a specific
RUN command.

[Support] Improve Windows performance of buffered raw_ostream
The "preferred" buffer size for raw_ostream is set to BUFSIZ which on
Windows is only 512. This results in more calls to write and this
overhead can have a significant negative impact on performance,
especially when Anti-Virus is also involved.
Therefore increase the "preferred" buffer size to 16KB for Windows.
One example of where this helps is the LLD --Map option which dumps out
the symbol map for a link. In a link of UE4, this change has been seen
to improve the performance of the symbol map writing by more than a
factor of 6.

[clang] Fix crash when handling nested immediate invocations
Before this patch it was expected that if there was several immediate
invocations they all belong to the same expression evaluation context.
During parsing of non local variable initializer a new evaluation context is
pushed, so code like this
```
namespace scope {
struct channel {
consteval channel(const char* name) noexcept { }
};
consteval const char* make_channel_name(const char* name) { return name;}
channel rsx_log(make_channel_name("rsx_log"));
}
```
produced a nested immediate invocation whose subexpressions are attached
to different expression evaluation contexts. The constructor call
belongs to TU context and `make_channel_name` call to context of
variable initializer.
This patch removes this assumption and adds tracking of previously
failed immediate invocations, so it is possible when handling an
immediate invocation th check that its subexpressions from possibly another
evaluation context contains errors and not produce duplicate
diagnostics.

[LICM] Don't require optimized uses
LICM currently requests optimized use MSSA form. This is wasteful,
because LICM doesn't actually care about most uses, only those of
invariant pointers in loops. Everything else doesn't need to be
optimized.
LICM already uses the clobber walker in most places. This patch
adjusts one place that was using getDefiningAccess() to use it as
well, so we no longer have a dependence on pre-optimized uses.
This change is not NFC in that the fallback on the defining access
when there are too many clobber calls may now fall back to an
unoptimized use. In practice, I've not seen any problems with this
though. If desired, we could also increase licm-mssa-optimization-cap
to a higher value (increasing this from 100 to 200 has no impact on
average compile-time -- but also doesn't appear to have any impact
on LICM quality either).
