Under certain circumstances, tryBuildVectorShuffle would attempt to
create a BUILD_VECTOR node with an invalid combination of types.
This happened when one of the components of the original BUILD_VECTOR
was itself a TRUNCATE node. That TRUNCATE was stripped off during
intermediate processing to simplify code, but when adding the node
back to the result vector, we still need it to get the type right.

Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).
For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.
This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.
This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

The first test (call) is now the only test to use .text, which makes it
resistant to more tests being added.
llvm-objdump -d already prints the addresses of symbols. We can use that in the
tests.

Patch improves codegen for OpenMP constructs. If the OpenMP region does not have internal 'cancel' construct, a call to 'void __kmpc_barrier()' runtime function is generated for all implicit/explicit barriers. If the region has inner 'cancel' directive, then
```
if (__kmpc_cancel_barrier())
exit from outer construct;
```
code is generated.
Also, the code for 'canellation point' directive is not generated if parent directive does not have 'cancel' directive.

Summary:
CMICmdArgSet stores a vector of non-const pointers to the arguments
that it is validating. It owns them and is responsible for deleting
them.
We don't need to pass a const reference to the argument to
CMICmdArgSet::Add and then take the address and const_cast it
when we can just pass the argument pointer in directly.
This lets us remove some noise at every call site for CMICmdArgSet::Add
and then clean up a couple of bits inside CMICmdArgSet to remove
const_casts.

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:
Added support for the following instructions:
CACHEE, LBE, LBUE, LHE, LHUE, LWE, LLE, LWLE, LWRE, PREFE,
SBE, SHE, SWE, SCE, SWLE, SWRE, TLBINV, TLBINVF
This required adding some infrastructure for the EVA ASE.

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.
llvm-svn: 247660
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).
