Summary:
* SharedDataDestroy couldn't fail, so no need to return a status.
* No need for status, so can remove error message. The error message
wasn't displayed or used anywhere anyway.

SUMMARY:
This patch provides support for MIPS specific DT_MIPS_RLD_MAP_REL tag in LLDB.
This tag allows debugging of MIPS position independent executables and provides access to shared library information.

Marked XFAIL for:
clang - all versions < 3.5. I verified the first version it passes on Linux is 3.5.
clang - version 3.7 (verified this fails)
clang - TOT/3.8 (verified this currently fails)
Ideally we dig into why this started failing and (hopefully) get this passing again.

Summary:
This was int64_t, but all usages of it came from code that was passing
in unsigned values. The usages of the array size, except for one, were
also treating it as an unsigned value. The usage that treated it as
signed was to try to figure out if it was a complete type or not, but
the callers creating the array didn't seem to be aware of using -1 as
an indicator for an incomplete array.

The values for the char/short/integer/long minimums were declared with
their actual values, not the definitions from the CL spec (v1.1). As
a result, (-2147483648) was actually being treated as a long by the
compiler, not an int, which caused issues when trying to add/subtract
that value from a vector.
Update the definitions to use the values declared by the spec, and also
add explicit casts for the char/short/int minimums so that the compiler
actually treats them as shorts/chars. Without those casts, they
actually end up stored as integers, and the compiler may end up storing
the INT_MIN as a long.
The compiler can sign extend the values if it needs to convert the
char->short, short->int, or int->long
v2: Add explicit cast for INT_MIN and fix some type-o's and wrapping
in the commit message.

r247657 fixed warnings about unused variables when compiling without asserts
but changed behavior. This commit restores the old behavior but still suppresses
the warnings.

Summary:
This change lets a `PlaceSafepoints` client change how wide the trip
count of a loop has to be for the loop to be considerd "counted", via
`CountedLoopTripWidth`. It also removes the boolean `SkipCounted` flag
and the `upperTripBound` constant -- we can get the old behavior of
`SkipCounted` == `false` by setting `CountedLoopTripWidth` to `13` (2 ^
13 == 8192).

In Objective-C, method calls with nil receivers are essentially no-ops. They
do not fault (although the returned value may be garbage depending on the
declared return type and architecture). Programmers are aware of this
behavior and will complain about a false alarm when the analyzer
diagnoses API violations for method calls when the receiver is known to
be nil.
Rather than require each individual checker to be aware of this behavior
and suppress a warning when the receiver is nil, this commit
changes ExprEngineObjC so that VisitObjCMessage skips calling checker
pre/post handlers when the receiver is definitely nil. Instead, it adds a
new event, ObjCMessageNil, that is only called in that case.
The CallAndMessageChecker explicitly cares about this case, so I've changed it
to add a callback for ObjCMessageNil and moved the logic in PreObjCMessage
that handles nil receivers to the new callback.

Previously, in certain cases lax vector conversions could occur between scalar floating-point values and ExtVector types; these conversions would be simple bitcasts. We need to allow them with other vector types to support some common headers, but we don't need them for ExtVector. Preventing them here makes them behave like other operations involving scalars and ExtVectors.

There is no __cxa_finalize symbol available on recent Solaris OS
versions, so we need this flag to make non trivial C++ programs run.
Also stop looking for cxa_finalize.o, since it won't be there.

Linux/clang on clang 3.6+ is passing this test. As OS X was
in a similar position, I'm guessing this was fixed by a recent
compiler. Might work on 3.5/3.4, but it is definitely working
on clang 3.6. I didn't break out FreeBSD since this appears to
be related to a compiler fix.

Summary: This change generalizes symlink generation and makes symlinks to tools obey LLVM_TOOLCHAIN_TOOLS. It makes it so that if you exclude llvm-ar from LLVM_TOOLCHAIN_TOOLS you don't end up with broken symlinks to llvm-lib and llvm-ranlib in your install.

WebAssembly's spec has now been updated to specify some guarantees
about lock free atomic accesses. Update clang to match.
This also updates sig_atomic_t to be 64-bit on wasm64. WebAssembly
does not presently have asynchronous interrupts, but this change is
within the spirit of how they will work if they are added.
