This is matching what trunk gcc is accepting. Also adds a missing ssse3
case. PR27779. The amount of duplication here is annoying, maybe it
should be factored into a separate .def file?

Summary:
This change automatically sorts ES6 imports and exports into four groups:
absolute imports, parent imports, relative imports, and then exports. Exports
are sorted in the same order, but not grouped further.

To keep JS import sorting out of Format.cpp, this required extracting the
TokenAnalyzer infrastructure to separate header and implementation files.

Some people have weird CI systems that run each test subdirectory
independently without access to other parallel trees.

Unfortunately, this means we have to suffer some duplication until Art
can sort out how to share these types.

The lexer sets the end location of macro arguments incorrectly *if*,
while merging consecutive args to fit into a single SLocEntry, it finds
args which come from different macro files.

Fix the issue by using separate SLocEntries in this situation.

This fixes a code coverage crasher (rdar://problem/26181005). Because
the lexer reported end locations for certain macro args incorrectly, we
would generate bogus coverage mappings with negative line offsets.

[analyzer] Fix for PR23790 : constrain return value of strcmp() rather than returning a concrete value.

The function strcmp() can return any value, not just {-1,0,1} : "The strcmp(const char *s1, const char *s2) function returns an integer greater than, equal to, or less than zero, accordingly as the string pointed to by s1 is greater than, equal to, or less than the string pointed to by s2."

Summary:
Previously it was implemented as inline asm in the CUDA headers.

This change allows us to use the [addr+imm] addressing mode when
executing ld.global.nc instructions.  This translates into a 1.3x
speedup on some benchmarks that call this instruction from within an
unrolled loop.

According to Cuda Programming guide (v7.5, E2.3.1):
> __device__, __constant__ and __shared__ variables defined in namespace
> scope, that are of class type, cannot have a non-empty constructor or a
> non-empty destructor.

Clang already deals with device-side constructors (see D15305).
This patch enforces similar rules for destructors.

Codegen tests for device-side variable initialization are subset of test
cases used to verify Sema's part of the job.
Including CodeGenCUDA/device-var-init.cu from SemaCUDA makes it easier to
