It appears the code uses nullptr to represent a void type in debug metadata,
which led to an assertion failure when building DeltaAlgorithm.cpp with a
self-hosted clang on Windows.
I'm not sure why/if the problem was Windows-specific.

Work towards the unification of MIR and debug output by refactoring the
interfaces.
Also add support for printing with a null TargetIntrinsicInfo and no
MachineFunction.

Summary:
We use Diagnostic as a key to find the corresponding FixIt when we do
the "apply-fix", but the "severity" field could be omitted, in some cases,
the codeAction request sent from LSP clients (e.g. VScode) doesn't include the
`severity` field, which makes clangd fail to find the FixIt.
Test the following code in VScode, before the fix, no FixIt shown.
```
void main() {}

Store data relocations with their respective segment.
This allows relocations to be applied as each segment
is written (and therefore in parallel).

Another followup to my refactoring in r321036: Turns out we can end up
with an x86 darwin target that is not macos (simulator triples can look
like i386-apple-ios) so we need the x86/32bit check in all cases.

OS instead of inferring it from SDK / environment
The OS version is specified in -target should be used instead of the one in an
environment variable / SDK name.

The Clang option -foptimization-record-file= controls which file an
optimization record is output to. Optimization records are output if you
use the Clang option -fsave-optimization-record. If you specify the
first option without the second, you get a warning that the command line
argument was unused. Passing -foptimization-record-file= should imply
-fsave-optimization-record.

Summary:
Extend overlapping store elision to handle overwrites of stores by
larger stores.
Nontemporal tests have been modified to add memory dependencies to
prevent store elision.

Going to add unit tests in the next patch. (Haha!) But seriously there's
some work to do first - need to extract the markers-in-source-code
parser from CodeComplete test and make it more flexible, to allow
annotated ranges etc.

We try to prevent shuffle combining to value types that would stop the folding of masked operations, but by just returning early, we were failing to try different shuffle types.
The TODOs are all still relevant here to improve codegen but we're lacking test examples.

Negative values never disabled the pruning - they simply set high values for the pruning interval.
The behaviour now is that negative values set the maximum pruning interval (which appears to have been the intention from the start) see https://reviews.llvm.org/D41231.
I have adjusted the comments to reflect this, removed any inaccurate statements, and corrected any typos I spotted in the English.

borked by: rL284966 (see: https://reviews.llvm.org/D25730).
Previously, Interval was unsigned (see: CachePruning.h), replacing the type with std::chrono::seconds (which is signed) causes a regression in behaviour because the c-api intends negative values to translate to large positive intervals to *effectively* disable the pruning (see comments on: setCachePruningInterval()).

As mentioned in D38318 and D40865, modern Intel processors prefer to combine multiple shuffles to a variable shuffle mask (PSHUFB/VPERMPS etc.) instead of having multiple stage 'fixed' shuffles which put more pressure on Port 5 (at the expense of extra shuffle mask loads).
This patch provides a FeatureFastVariableShuffle target flag for Haswell+ CPUs that prefers combining 2 or more fixed shuffles to a single variable shuffle (default is 3 shuffles).
The long term aim is to drive more of this from schedule data (probably via the MC) but we're not close to being ready for that yet.

Summary:
- Moved these functions to SourceCode.h
- added unit tests
- fix off by one in positionToOffset: Offset - 1 in final calculation was wrong
- fixed formatOnType which had an equal and opposite off-by-one
- positionToOffset and offsetToPosition both consistently clamp to beginning/end
of file when input is out of range
- gave variables more descriptive names
- removed windows line ending fixmes where there is nothing to fix
- elaborated on UTF-8 fixmes
This will conflict with Eric's D41281, but in a pretty easy-to-resolve way.
