Richard Sandiford b86a83488e [SystemZ] Add conditional store patterns
Add pseudo conditional store instructions, so that we use:

    branch foo:
    store
foo:

instead of:

    load
    branch foo:
    move
foo:
    store

z196 has real 32-bit and 64-bit conditional stores, but we don't use
any z196 instructions yet.

This is essentially reverting one piece of 184793 to try to fix one of Apple's
buildbots.  I will check with Eric to see if this is OK or if we need to find
some other solution.

Rafael Espindola 7ffacc4992 Add a convenience createUniqueDirectory function.
There are a few valid situation where we care about the structure inside a
directory, but not about the directory itself. A simple example is for unit
testing directory traversal.

PathV1 had a function like this, add one to V2 and port existing users of the
created temp file and delete it hack to using it.

Sean Callanan 85fc876106 Fixed the IRInterpreter to reject any code that
has more than one function with a body.  This
prevents declarations e.g. of blocks from being
passed to the IRInterpreter; they must pass
through to the JIT.

Sean Callanan ffae944a39 Fixed IRExecutionUnit so that it looks up addresses
correctly.  We have been getting lucky since most
expressions generate only one section (or the first
code section contains all the code), but sometimes
it actually matters.

Arnold Schwaighofer ccd6c9929b LoopVectorize: Don't store a reversed value in the vectorized value map
When we store values for reversed induction stores we must not store the
reversed value in the vectorized value map. Another instruction might use this
value.

This fixes 3 test cases of PR16455.

Sean Callanan 70cac8fd81 Remove the process's reservation cache and don't
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.

Eli Friedman 437313c26f Handle all TemplateArguments in trivial TypeLocs.
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.)

Michael Gottesman 8136c384c5 [APFloat] Convert all references to fcNormal to references to isFiniteNonZero().
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().

Option groups don't have prefixes.  Option dumping is basically dead

Stephen Lin ff7fceed7d 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)

Eli Friedman 2782dacfbc Rewrite record layout for ms_struct structs.
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.
