We didn't supporting taking the address of virtual member functions
which overrode a method in a virtual base. We simply need to encode the
virtual base index in the member pointer.
This fixes PR23452.
N.B. There is no data member pointer side to this change because taking
the address of a virtual bases' data member gives you a member pointer
whose type is derived from the virtual bases' type, not the most derived
type.

MSVC 2015 renamed the symbol found by name lookup for 'std::terminate'
so we cannot rely on using '?terminate@@YAXXZ'. Furthermore, it seems
that 2015 will be the first release of MSVC which permits inlining a
function which is noexcept into a function which isn't. This is
implemented by creating a cleanup for the invoker which jumps to
__std_terminate. Clang's implementation of this aspect of the MSVC
scheme is slightly less efficient in this respect because we use a
catch handler configured as a catch-all handler instead.

Test Plan: run tests with/without python debugger
Tested on OSX & Linux with PyCharm

Summary:
New dotest options that allow arbitrary log channels and
categories to be enabled. Also enables logging for locally run
debug servers.
Log messages are separated into separate files per test case.
(this makes it possible to log in dosep runs)
These new log files are stored side-by-side with trace files in the
session directory.
These files are deleted by default if the test run is successful.
If --log-success is specified, even successful logs are retained.
--log-success is useful for creating reference log files.
Test Plan:
add '--channel "lldb all" --channel "gdb-remote packets" --log-success'
to your dotest options
Tested on OSX and Linux

Second attempt; instead of using a named local variable, passing
arguments directly to `createSanitizerCtorAndInitFunctions` worked

Some compilers ignore everything after a semicolon in such inline asm
blocks and thus, the closing brace must not be moved to the previous
line.

So cmake will throw error "include_directories given empty-string as include directory".
Use other variable name for the include path and do not find the default libunwind.h in the system path.

Converts the MAP_PRIVATE and MAP_ANON options to the target platform constants
(on which the call runs) rather than using those of the compiled host.
Test Plan:
Run test suite, the following tests requiring memory allocation / JIT support
begin passing when running mac -> linux:
Test11588.py
TestAnonymous.py
TestBreakpointConditions.py
TestCPPStaticMethods.py
TestCStrings.py
TestCallStdStringFunction.py
TestDataFormatterCpp.py
TestDataFormatterStdList.py

Upcoming revisions of isl require us to include header files explicitly, which
have previously been already transitively included. Before we add them, we sort
the existing includes.
Thanks to Chandler for sort_includes.py. A simple, but very convenient script.

Changes:
- Add "isl/" as a system library prefix. Even though isl is regularly
imported into polly, it is still used like an external library.
- Add "json/" as a system library prefix. Polly uses json-cpp as external
library.
- Distinguish between llvm and subproject libraries. Always sort subprojects
before LLVM. This was already the case with clang, as 'clang' comes before
'llvm', but we also want 'polly' to be sorted before 'llvm'.
The sorting of headers that are not part of Polly or isl remains unchanged.

The bug showed up as a compile-time assertion failure:
Assertion `NumBits >= MIN_INT_BITS && "bitwidth too small"' failed
when building msan tests on x86-64.
Prior to r236850, this bug was masked due to a bogus alignment check,
which also accidentally rejected non-byte-sized accesses. Afterwards,
an invalid ElementSizeBytes == 0 got further into the function, and
triggered the assertion failure.
It would probably be a good idea to allow it to handle merging stores
of unusual widths as well, but for now, to un-break it, I'm just
making the minimal fix.

XFAILing these does not work because the timeout is caught by the
top-level test infrastucture instead.

When emitting something like 'add x, 1000' if we remat the 1000 then we should be able to
mark the vreg containing 1000 as killed. Given that we go bottom up in fast-isel, a later
use of 1000 will be higher up in the BB and won't kill it, or be impacted by the lower kill.
However, rematerialised constant expressions aren't generated bottom up. The local value save area
grows downwards. This means that if you remat 2 constant expressions which both use 1000 then the
first will kill it, then the second, which is *lower* in the BB will read a killed register.
This is the case in the attached test where the 2 GEPs both need to generate 'add x, 6680' for the constant offset.
Note that this commit only makes kill flag generation conservative. There's nothing else obviously wrong with
the local value save area growing downwards, and in fact it needs to for handling arbitrarily complex constant expressions.
However, it would be nice if there was a solution which would let us generate more accurate kill flags, or just kill flags completely.

This implementation was ported from the AMD builtin library
and has been tested with piglit, OpenCV, and the ocl conformance tests.
v2:
- Remove f suffix from constant in double implementations.
- Consolidate implementations using the .cl/.inc approach.
v3:
- Use __CLC_FPSIZE instead of __CLC_FP{32,64}
v4 (Jan Vesely):
- Limit to single precision.

The code that builds the dependence graph assumes that two PseudoSourceValues
don't alias. In a tail calling function two FixedStackObjects might refer to the
same location. Worse 'immutable' fixed stack objects like function arguments are
not immutable and will be clobbered.
Change this so that a load from a FixedStackObject is not invariant in a tail
calling function and don't return a PseudoSourceValue for an instruction in tail
calling functions when building the dependence graph so that we handle function
arguments conservatively.
Fix for PR23459.
