Checking with truss reveals that this is the same issue as on AIX and
documented in chmod(2):
If the process is not a privileged process and the file is not a direc-
tory, mode bit 01000 (S_ISVTX, the sticky bit) is cleared.
The following patch fixes this in the same way. Tested on amd64-pc-solaris2.11.

Summary:
These are output by clang -S, so can now be roundtripped thru clang.

MVE adds the lsll, lsrl and asrl instructions, which perform a shift on a 64 bit value separated into two 32 bit registers.
The Expand64BitShift function is modified to accept ISD::SHL, ISD::SRL and ISD::SRA and convert it into the appropriate opcode in ARMISD. An SHL is converted into an lsll, an SRL is converted into an lsrl for the immediate form and a negation and lsll for the register form, and SRA is converted into an asrl.
test/CodeGen/ARM/shift_parts.ll is added to test the logic of emitting these instructions.

We were requiring that both shuffle operands were EXTRACT_SUBVECTORs, but we can relax this to only require one of them to be.
Also, we shouldn't bother attempting this if both operands are from the lowest subvector (or not EXTRACT_SUBVECTOR at all).

This simply adds integer and floating point VMUL patterns for MVE, same as we
have add and sub.

This adds handling and tests for a number of floating point math routines,
which have no MVE instructions.

Delete unnecessary getters of AddressRange.
Simplify AddressRange::size(): Start <= End check should be checked in an upper layer.
Delete isContiguousWith() that doesn't make sense.
Simplify AddressRanges::insert. Delete commented code. Fix it when more than 1 ranges are to be deleted.
Delete trailing newline.

MVE has instructions to widen as it loads, and narrow as it stores. This adds
the required patterns and legalisation to make them work including specifying
that they are legal, patterns to select them and test changes.
Patch by David Sherwood.

This fills in the gaps for basic MVE loads and stores, allowing unaligned
access and adding far too many tests. These will become important as
narrowing/expanding and pre/post inc are added. Big endian might still not be
handled very well, because we have not yet added bitcasts (and I'm not sure how
we want it to work yet). I've included the alignment code anyway which maps
with our current patterns. We plan to return to that later.
Code written by Simon Tatham, with additional tests from Me and Mikhail Maltsev.

We don't have vector operations for these, so they need to be expanded for both
integer and float.

The same as integer arithmetic, we can add simple floating point MVE addition and
subtraction patterns.

Introduce llvm.test.set.loop.iterations which sets the loop counter
and also produces an i1 after testing that the count is not zero.

This adds the first few patterns for MVE code generation, adding simple integer

This patch adds necessary shuffle vector and buildvector support for ARM MVE.
It essentially adds support for VDUP, VREVs and some VMOVs, which are often
required by other code (like upcoming patches).
This mostly uses the same code from Neon that already generated
NEONvdup/NEONvduplane/NEONvrev's. These have been renamed to ARMvdup/etc and
moved to ARMInstrInfo as they are common to both architectures. Most of the
selection code seems to be applicable to both, but NEON does have some more
instructions making some parts specific.
Most code originally by David Sherwood.

Summary: This patch changes fs::setPermissions to optionally set permissions while respecting the umask. It also adds the function fs::getUmask() which returns the current umask.

The new switch lowering code that tries to generate jump tables and range checks
were tested at -O0 on arm64, but on -O3 the generic switch lowering code goes to
town on trying to generate optimized lowerings, e.g. multiple jump tables, range
checks etc. This exposed bugs in the way PHI nodes are handled because the CFG
looks even stranger after all of this is done.

Summary:
Current InlineCost is not assignable because of const members Cost and Threshold.
I dont see practical benefits from having them const (access to these members is
private and internal interactions are rather simple). On other hand that makes
it hard to use as a member in some other data structure where assignability is necessary.
I'm going to use InlineCost in a downstream inliner that maintains a complex queue
of candidate call-sites and thus keeping and recalculating InlineCost is necessary.
This patch just removes 'const' from both members, making InlineCost assignable.
