D60041 / D60138 refactoring changed how CMOV/SETcc opcodes

This at least allows to not crash on the opcode.
However, this still won't generate all the snippets
with all the condcode enumerators. D60066 does that.

[CMake] Don't explicitly use LLVM_LIBRARY_DIR in standalone builds
Summary:
This line is unnecessary because add_llvm_executable will handle
linking the correct LLVM libraries for you. LLDB standalone builds are totally
fine without this.
In the best case, having this line here is harmless. In the worst case it can
cause link issues.
If you build lldb-server for android using the standalone build, this line
will cause LLVM_LIBRARY_DIR to be the first place you look for libraries.
This is an issue because if you built libc++, it will try to link against
that one instead of the one from the android NDK. Meanwhile, the LLVM libraries
you're linking against were linked against the libc++ from the NDK.
Ideally, we would take advantage of the AFTER option for link_directories(), but
that was not available in LLDB's minimum supported version of CMake (CMake 3.4.3).

contract, and it's unlikely that the header function has accidentally
forgot to put the value into the out-parameter; it's more likely

[IMPORTANT]
With that last fix, CUDA has just started being compiling by clang on Windows after nearly a year and two clang’s major releases (7 and 8).
As long as the last LLVM release, in which clang was compiling CUDA on Windows successfully, was 6.0.1, this fix and two previous have to be included into upcoming 7.1.0 and 8.0.1 releases.

Add missing long double device functions' declarations. Provide only declarations to prevent any use of long double on the device side, because CUDA does not support long double on the device side.

[libc++] Fix error flags and exceptions propagated from input stream operations
Summary:
This is a re-application of r357533 and r357531. They had been reverted
because we thought the commits broke the LLDB data formatters, but it
turns out this was because only r357531 had been included in the CI
run.
Before this patch, we would only ever throw an exception if the badbit
was set on the stream. The Standard is currently very unclear on how
exceptions should be propagated and what error flags should be set by
the input stream operations. This commit changes libc++ to behave under
a different (but valid) interpretation of the Standard. This interpretation
of the Standard matches what other implementations are doing.
This effectively implements the wording in p1264r0. It hasn't been voted
into the Standard yet, however there is wide agreement that the fix is
correct and it's just a matter of time before the fix is standardized.

[TextAPI] Fix off-by-one error in the bit index extraction loop
The loop in findNextSetBit() runs one pass more than it should.
On 64-bit architectures this does not cause a problem, but 32-bit
architectures mask the shift count to 5 bits which limits the number of
shifts inside a range of 0 to 31. Shifting by 32 has the same effect as
shifting by 0, so if the first bit in the set is 1, the function will return
with Index different from EndIndexVal. Because of that, range-based for
loops iterating thorough architectures will continue until hitting a 0 in
the set, resulting in n additional iterations, where n is equal to the
number of consecutive 1 bits at the start the set.
Ultimately TBDv1.WriteFile and TBDv2.WriteFile will output additional

Minidump: Add support for reading/writing strings
Summary:
Strings in minidump files are stored as a 32-bit length field, giving
the length of the string in *bytes*, which is followed by the
appropriate number of UTF16 code units. The string is also supposed to
be null-terminated, and the null-terminator is not a part of the length
field. This patch:
- adds support for reading these strings out of the minidump file (this
implementation does not depend on proper null-termination)
- adds support for writing them to a minidump file
- using the previous two pieces implements proper (de)serialization of
the CSDVersion field of the SystemInfo stream. Previously, this was
only read/written as hex, and no attempt was made to access the
referenced string -- now this string is read and written correctly.
The changes are tested via yaml2obj|obj2yaml round-trip as well as a
unit test which checks the corner cases of the string deserialization
logic.

This also removes some checked-in binaries which were used to test error
