Introduce KMP_DEVICE_THREAD_LIMIT
This change drops in KMP_DEVICE_THREAD_LIMIT to replace KMP_MAX_THREADS. It's
possible there will eventually be a OMP_DEVICE_THREAD_LIMIT, and we need
something to distinguish from OMP_THREAD_LIMIT, which is currently implemented
incorrectly (the fix for that will be added soon in a separate patch).
KMP_ALL_THREADS is deprecated here, but we can keep the "all" option on
KMP_DEVICE_THREAD_LIMIT to support that functionality. KMP_DEVICE_THREAD_LIMIT
now has priority over its deprecated rival KMP_ALL_THREADS. I also cleaned up
some comments that incorrectly referred to non-existent kmp_max_threads variable
instead of kmp_max_nth.
I've left the name of where this setting eventually ends up as
__kmp_max_nth, for now.
This change does not change much in the way of functionality. It does NOT change
OMP_THREAD_LIMIT. It's just cleaning up and setting up for that.

Do a better job at emitting prefrabricated skeleton CUs.
This is a better fix than r308708 for the problem introduced in
r304020. It restores the skeleton CU testcases modified by that commit
to their original form and most importantly ensures that
frontend-generated skeleton CUs (such as used to point to Clang
modules) come after the regular CUs. This broke for DICompileUnit
nodes that don't have any immediate children because they are now
constructed lazily instead of the order in which they are listed in
!llvm.dbg.cu. After this commit we still don't guarantee that order,
but we do guarantee that empty skeletons come last.
Shipping versions of LLDB are very sensitive to the ordering of
CUs. I'll track a fix for LLDB to be more permissive separately.

Recommit r308327 2nd time: Add a warning for missing
'#pragma pack (pop)' and suspicious uses of '#pragma pack' in included files
The first recommit (r308441) caused a "non-default #pragma pack value might
change the alignment of struct or union members in the included file" warning
in LLVM itself. This recommit tweaks the added warning to avoid warnings for
#includes that don't have any records that are affected by the non-default
alignment. This tweak avoids the previously emitted warning in LLVM.
Original message:
This commit adds a new -Wpragma-pack warning. It warns in the following cases:
- When a translation unit is missing terminating #pragma pack (pop) directives.
- When entering an included file if the current alignment value as determined
by '#pragma pack' directives is different from the default alignment value.
- When leaving an included file that changed the state of the current alignment
value.

[COFF, ARM64] Fix symbol offsets in ADRP/ADD/LDR/STR relocations
In COFF, a symbol offset can't be stored in the relocation (as is
done in ELF or MachO), but is stored as the immediate in the
instruction itself. The immediate in the ADRP thus is the symbol
offset in bytes, not in pages. For the PAGEOFFSET_12A/L relocations,
ignore any offset outside of the lowest 12 bits; they won't have any
effect on the ADD/LDR/STR instruction itself but only on the associated
ADRP.
This is similar to how the same issue is handled for MOVW/MOVT
instructions in ELF (see e.g. SVN r307713, and r307728 in lld).
This fixes "fixup out of range" errors while building larger object
files, where temporary symbols end up as a plain section symbol and
an offset, and fixes any cases where the symbol offset mean that
the actual target ended up on a different page than the symbol
itself.

[globalisel][tablegen] Fuse the generated tables together.
Summary:
Now that we have control flow in place, fuse the per-rule tables into a
single table. This is a compile-time saving at this point. However, this will
also enable the optimization of a table so that similar instructions can be
tested together, reducing the time spent on the matching the code.
This is NFC in terms of externally visible behaviour but some internals have
changed slightly. State.MIs is no longer reset between each rule that is
attempted because it's not necessary to do so. As a consequence of this the
restriction on the order that instructions are added to State.MIs has been
relaxed to only affect recorded instructions that require new elements to be
added to the vector. GIM_RecordInsn can now write to any element from 1 to
State.MIs.size() instead of just State.MIs.size().

[X86][LLVM]Expanding Supports lowerInterleavedStore() in X86InterleavedAccess.
This patch expands the support of lowerInterleavedStore to 32x8i stride 4.
LLVM creates suboptimal shuffle code-gen for AVX2. In overall, this patch is a specific fix for the pattern (Strid=4 VF=32) and we plan to include more patterns in the future. To reach our goal of "more patterns". We include two mask creators. The first function creates shuffle's mask equivalent to unpacklo/unpackhi instructions. The other creator creates mask equivalent to a concat of two half vectors(high/low).
The patch goal is to optimize the following sequence:
At the end of the computation, we have ymm2, ymm0, ymm12 and ymm3 holding
each 32 chars:
c0, c1, , c31
m0, m1, , m31
y0, y1, , y31
k0, k1, ., k31
And these need to be transposed/interleaved and stored like so:
c0 m0 y0 k0 c1 m1 y1 k1 c2 m2 y2 k2 c3 m3 y3 k3 ....
