[SLP][NFC] Pre-commit test showing vectorization preventing FMA

When we generate a horizontal reduction of floating adds fed by a vectorized
tree rooted at floating multiplies, we should account for the cost of no
longer being able to generate scalar FMAs.  Similarly, if we vectorize a
list of floating multiplies that each feeds a single floating add, we should
again account for this cost.

The first test was reduced from a case where the vectorizable tree looked
barely profitable (cost -1) with a horizontal reduction, but produced
substantially worse code than allowing the FMAs to be generated.  The second
test was derived from the first: we again generate a horizontal reduction
here, but even if the horizontal reduction is forced to be unprofitable, we
try to vectorize the multiplies.  I have follow-up patches to address these
issues.

This fixes an issue seen on Windows where we did not properly
get the section names of regions if they overlapped. Windows
has regions like:
[0x00007fff928db000-0x00007fff949a0000) ---
[0x00007fff949a0000-0x00007fff949a1000) r-- PECOFF header

[0x00007fff949a0000-0x00007fff94a88000) rw- .data

[0x00007fff94a94000-0x00007fff95250000) ---

I assumed that you could just resolve the address and get the section
name using the start of the region but here you'd always get
"PECOFF header" because they all have the same start point.

The usual command repeating loop used the end address of the previous
region when requesting the next, or getting the section name.
So I've matched this in the --all scenario.

In the example above, somehow asking for the region at
0x00007fff949a1000 would get you a region that starts at
0x00007fff949a0000 but has a different end point. Using the load
address you get (what I assume is) the correct section name.

SourceLocations can be relatively large numbers, so this commonly takes
20-30 bits per location.

We can reduce this by exploiting redundancy: many "nearby" SourceLocations are

Randam-access loading of AST nodes constrains how long these sequences

deserialized as an atomic unit.

TypeLoc is implemented in this patch as it's a relatively small change

This saves ~3.5% of PCH size, I have local changes applying this technique

[libc++][format] Improve format-arg-store.

This optimizes the __format_arg_store type to allow a more efficient

It stores the data in two arrays:
- A struct with the tag of the exposition only variant's type and the
  offset of the element in the data array. Since this array only depends
  on the type information it's calculated at compile time and can be
  shared by different instances of this class.
- The arguments converted to the types used in the exposition only
  variant of basic_format_arg. This means the packed data can be
  directly copied to an element of this variant.

The new code uses rvalue reference arguments in preparation for P2418.
The handle class also has some changes to prepare for P2418. The real
changed for P2418 will be done separately, but these parts make it
easier to implement that paper.

Some parts of existing test code are removed since they were no longer

[MC] [Win64EH] Don't produce packed ARM64 unwind info with homed parameters

There's an inconsistency regarding the epilogs of packed ARM64
unwind info with homed parameters; according to the documentation
(and according to common sense), the epilog wouldn't have a series
of nop instructions matching the stp x0-x7 in the prolog - however
in practice, RtlVirtualUnwind still seems to behave as if the epilog
does have the mirrored nops from the prolog.

In practice, MSVC doesn't seem to produce packed unwind info with
homed parameters, which might be why this inconsistency hasn't
been noticed.

Thus, to play it safe, avoid creating such packed unwind info with
homed parameters. (LLVM's current behaviour matches the current
runtime behaviour of RtlVirtualUnwind, but if it later is bug fixed

incorrect.)

Previously, the same issue was dealt with by setting a project wide

_LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS) if only building a static

wasn't set, and the static library would contain dllexport directives.

options only apply the defines to the static library in the build,
even if building both static and shared at the same time.

(This could only be done use after the object libraries were
enabled, as a shared libcxx needs libcxxabi object files built

users should need to start setting an option, which they shouldn't
need to. Finally, this gets rid of two XFAILs in tests.

Now, these bits are unset by default. Setting them will always result in the dialect generator emitting the declarations for the parsing hooks. And if the AttrOrTypeDef generator sees it set, it will generate the default implementations.
