Summary:
Instead of using `AlignedChunkHeaderSize`, introduce a `constexpr` function
`getHeaderSize` in the `Chunk` namespace. Switch `RoundUpTo` to a `constexpr`
as well (so we can use it in `constexpr` declarations). Mark a few variables
in the areas touched as `const`.
Overall this has no functional change, and is mostly to make things a bit more
consistent.

I'm not sure whether there are any principal reasons why it returns raw owning pointer,
or it is just a old code that was not updated post-C++11.
I'm not too sure what testing i should do, because `check-all` is not error clean here for some reason,
but it does not //appear// asif those failures are related to these changes.
This is Clang-tools-extra part.

ObjC defines `@autoreleasepool` and `@synchronized` control blocks. These
used to be formatted according to the `AfterObjCDeclaration` brace-
wrapping flag, which is not very consistent.
This patch changes the behavior to use the `AfterControlStatement` flag
instead. This should not affect the behavior unless a custom brace
wrapping mode is used.

llvm-svn: 326192
Summary:
The blocks used to be formatted using the "default" behavior, and would
thus be mistaken for function calls followed by blocks: this could lead
to unexpected inlining of the block and extra line-break before the
opening brace.
They are now formatted similarly to `@autoreleasepool` blocks, as
expected:
@synchronized(self) {
f();
}

Summary:
Since r325479 the DataLayout includes a program address space. However, it
is not possible to use `call %foo` if foo is a `i8(...) addrspace(200)` and
the DataLayout specifies address space 200 as the address space for functions.
With this change the IR parser will still accept variables in the program
address space as well as address space 0 for call and invoke functions.

Add test that verifies that we don't follow DWARF values with a
reference form class, such as DW_AT_sibling.
Since clang doesn't generate the latter attribute, we added a PowerPC
test generated on an old PowerBook G4. (Thanks Adrian!)
llvm-svn: 326183
Until this patch, only `powerpc` and `ppc32` were recognized as valid
PowerPC 32-bit architectures in a target triple. This was incompatible
with the triple `ppc-apple-darwin` as returned for libObject. I found
out about this when working on a test case using a binary generated on
an old PowerBook G4.
We had the choice of either fix this in the Mach-O object parser or
in the Triple implementation. I chose the latter because it feels like
the most canonical place.

In case we update a ValuePHI node created earlier, we could update it
based on a different OpPHI which could be in a different block.
We need to update the TempToBlock mapping reflecting the new block,
otherwise we would end up placing the new phi node in a wrong block.
This problem is exposed by the test case in
https://bugs.llvm.org/show_bug.cgi?id=36504.
This patch fixes a slightly simpler problem than in the bug report. In
the bug's re-producer, the additional problem is that we are re-using a
ValuePHI node with to few incoming values for the new OpPHI. If this
patch makes sense, I will follow it up with a patch that creates a new
PHI node if the existing PHI node has a different number of incoming
values.

Imagine that we have sections A, B, C, where A == C and
symbol ordering file containing symbols: symC, symB, symA
Previously because of ICF it was possible that final order would be
B, A or B, C. That violates order specified in ordering file.
Patch changes that.

The only cases I can come up with where this invalidation needs to
happen is when there's a deletion somewhere. If we find more creative
test-cases, we can probably go with another approach mentioned on
PR36529.

It appears that there were many cases where we were directly (through
templates) calling the dtor of MemoryAccess, which is conceptually an
abstract class.
This hasn't been a problem, since the data members of all of the
subclasses of MemoryAccess have been POD. I'm planning on changing that.

Set default value for IgnoreOtherLoops of SCEVInitRewriter::rewrite to true

When targeting GNU/MinGW for i386, the size of the "long double" data
type is 12 bytes (while it is 8 bytes in MSVC). When building
with -mms-bitfields to have struct layouts match MSVC, data types
are laid out in a struct with alignment according to their size.
However, this doesn't make sense for the long double type, since
it doesn't match MSVC at all, and aligning to a non-power-of-2
size triggers other asserts later.
This matches what GCC does, aligning a long double to 4 bytes
in structs on i386 even when -mms-bitfields is specified.
This fixes asserts when using the max_align_t data type when
building for MinGW/i386 with the -mms-bitfields flag.

macOS home directory paths begin with /Users, and clang-cl interprets
the /U portion as a macro undefine rather than a path, causing test
failures on macOS. Use a -- to explicitly treat the input file as a path
and fix the test.
This effectively reverts r326168 and adds an alternative fix.

These tests all test very similar things, and use the same inferior.
They were only placed in separate folders to achieve better
paralelization. Now that we paralelize at a file level, this is no
longer relevant, and we can put them together again.

AVX512 used to promote v32i1 to v32i8 during legalization when BWI was disabled. So this code was added to improve legalization of v32i1 concat_vectors of v16i1 by extending the v16i1 to v16i8 to avoid scalarization.
X86 has since switched to legalizing v32i1 by splitting to v16i1 instead. This has rendered this code unnecessary and its no longer exercised.
