[APFloat] Added unittest for APFloat.divide that checks special cases, result categories, and result statuses.

The Builtin attribute is an attribute that can be placed on function call site that signal that even though a function is declared as being a builtin,

Found a race condition when killing an application where the state could be set to exited by the waitpid_thread() _before_ we call task resume (via MachProcess::PrivateResume()) in MachProcess::Kill().

bother checking if a region is safe to use.  In
cases where regions need to be synthesized rather
than properly allocated, the memory reads required
to determine whether the area is used are

- insufficient, because intermediate locations
  could be in use, and

- unsafe, because on some platforms reading from
  memory can trigger events.

All this only makes a difference on platforms
where memory allocation in the target is impossible.
Behavior on platforms where it is possible should
stay the same.

SLP: When searching for vectorization opportunities scan the blocks in post-order because we grow chains upwards.

SLP: Dont erase instructions during vectorization because it prevents the outerloops from iterating over the instructions.

Armed with a much better understanding of what
TemplateSpecializationTypeLoc::initializeArgLocs actually does, I now
understand that it's fine to just use an empty TemplateArgumentLocInfo
for Integral, Declaration, and NullPtr TemplateArguments.

Fixes PR14281. (The testcases are actually derived from libcxx_test in
deduction-crash.cpp because the original testcase was impossible to reduce.)

In InstCombine{AddSub,MulDivRem} convert APFloat.isFiniteNonZero() && !APFloat.isDenormal => APFloat.isNormal.

llvm-svn: 185037

Currently inside APFloat fcNormal still implies the old definition of Normal
(i.e. isFiniteNonZero) instead of the proper IEEE-754R definition that the
external method isNormal() uses.

This patch prepares for the internal switch inside APFloat by converting all
references that check if a category is fcNormal directly with an indirect call
via isFiniteNonZero().

side-effect is not sequenced before its value computation. Also fix a
mishandling of ?: expressions where the condition is constant that was
exposed by the tests for this.

Option groups don't have prefixes.  Option dumping is basically dead
code unless there is something wrong with the option table, so this
isn't an important crasher.

ARM: Proactively ensure that the LowerCallResult hack for 'this'-returns is not used for incompatible calling conventions.

(Currently, ARM 'this'-returns are handled in the standard calling convention case by treating R0 as preserved and doing some extra magic in LowerCallResult; this may not apply to calling conventions added in the future so this patch provides and documents an interface for indicating such)

No functionality change.
It should suffice to check the type of a debug info metadata, instead of
calling Verify.

They are mostly duplicated and got out of sync during the PathV1 removal. We
should factor the code somewhere, but for now a FIXME will do.

The old implementation of ms_struct in RecordLayoutBuilder was a
complete mess: it depended on complicated conditionals which didn't
really reflect the underlying logic, and placed a burden on users of
the resulting RecordLayout. This commit rips out almost all of the
old code, and replaces it with simple checks in
RecordLayoutBuilder::LayoutBitField.

This commit also fixes <rdar://problem/14252115>, a bug where class
inheritance would cause us to lay out bitfields incorrectly.

Match up with top’s implementation on recent Cab as API has changed a bit.
Tested the same binary running on Zin as well. Tested ARM binary on iOS as well.

The assembly should be generic, but at least currently R600 only supports
32-bit stores of [u]int1/4, and I believe that only global is well-supported.

R600 lowers the 8/16 component stores to multiple 4-component stores.

The unoptimized C versions of the other stuff is left in place.
