I was bitten by this when working with the dll attributes: when a dll
attribute was cloned from a class template declaration to its
specialization, the Inherited flag didn't get cloned.

[X86] Add two combine rules to simplify dag nodes introduced during type legalization when promoting nodes with illegal vector type.

This patch teaches the backend how to simplify/canonicalize dag node
sequences normally introduced by the backend when promoting certain dag nodes
with illegal vector type.

This patch adds two new combine rules:
1) fold (shuffle (bitcast (BINOP A, B)), Undef, <Mask>) ->
        (shuffle (BINOP (bitcast A), (bitcast B)), Undef, <Mask>)

2) fold (BINOP (shuffle (A, Undef, <Mask>)), (shuffle (B, Undef, <Mask>))) ->
        (shuffle (BINOP A, B), Undef, <Mask>).

Both rules are only triggered on the type-legalized DAG.
In particular, rule 1. is a target specific combine rule that attempts
to sink a bitconvert into the operands of a binary operation.
Rule 2. is a target independet rule that attempts to move a shuffle
immediately after a binary operation.

Summary:
If both vector args to vselect are concat_vectors and the condition is
constant and picks half a vector from each argument, convert the vselect
into a concat_vectors.

Added a test.

The ConvertSelectToConcatVector is assuming it doesn't get vselects with
arguments of, for example, <undef, undef, true, true>. Those get taken
care of in the checks above its call.

Summary:
Separate the check for blend shuffle_vector masks into isBlendMask.
This function will also be used to check if a vector shuffle is legal. No
change in functionality was intended, but we ended up improving codegen on
two tests, which were being (more) optimized only if the resulting shuffle
was legal.

This reapplies r209910 with a fix for the assertion failures hit on the
buildbots.

original commit message:
I thought we could get away without this, but it means that the
FileEntry objects actually refer to the wrong files, since pcms are not
updated inplace, they are atomically renamed into place after compiling
a module.

So we are close to the original behaviour of invalidating the cache for
all modules being removed, but now we should only invalidate the ones
that depend on whichever module failed to load.

Unfortunately I haven't come up with a new test that didn't require
a race between parallel invocations of clang.

This helps more branches into selects. On R600,
vectors are cheap and anything that helps

Learned that MacOSX only accepts signal delivery on a thread that is
already signal handling.  Reworked the test exe to cause a SIGSEGV
and recover if either nothing intercepts the SIGSEGV handler, or
if a SIGUSR1 is inserted.  The test uses the latter part to test
signal delivery on continue using the SIGUSR1.

I still don't have this working on MacOSX.  I'm seeing the
signal get delivered to a different thread than the one I'm
specifying with $Hc{thread-id} + $C{signo}, or with
$vCont;C{signo}:{thread-id};c.  I'll come back to this
after getting it working on the llgs branch on Linux x86_64.

There was a single problem in cxa_demangle.cpp, where gcc would complain
`error: changes meaning of 'String'` about the line `typedef String String;`.
According to 3.3.7p2, this diagnostic is allowed (but not required, so clang
does not have to report this).

As a fix, make string_pair a template and pass String as template parameter.
This fixes the error with gcc and also removes some repetition from the code. 

No behavior change.

This implements the central part of support for dllimport/dllexport on
classes: allowing the attribute on class declarations, inheriting it
to class members, and forcing emission of exported members. It's based
on Nico Rieck's patch from http://reviews.llvm.org/D1099.

This patch doesn't propagate dllexport to bases that are template
specializations, which is an interesting problem. It also doesn't
look at the rules when redeclaring classes with different attributes,
I'd like to do that separately.

an indirect pointer to absptr; otherwise, some link warning
warning will be raised, and the program might crash in some
