Fix 'this' capturing Generic lambdas used within default initializers (PR19876)

http://llvm.org/bugs/show_bug.cgi?id=19876

The following C++1y code results in a crash:

struct X {
  int m = 10;
  int n = [this](auto) { return m; }(20);
};

When implicitly instantiating the generic lambda's call operator specialization body, Sema is unable to determine the current 'this' type when transforming the MemberExpr 'm' - since it looks for the nearest enclosing FunctionDeclDC - which is obviously null.

I considered two ways to fix this:

    1) In InstantiateFunctionDefinition, when the context is saved after the lambda scope info is created, retain the 'this' pointer.
    2) Teach getCurrentThisType() to recognize it is within a generic lambda within an NSDMI/default-initializer and return the appropriate this type.

I chose to implement #2 (though I confess I do not have a compelling reason for choosing it over #1).

Adam Nemet [Thu, 29 May 2014 20:47:29 +0000 (20:47 +0000)]
Implement AVX1 vbroadcast intrinsics with vector initializers

These intrinsics are special because they directly take a memory operand (AVX2
adds the register counterparts).  Typically, other non-memop intrinsics take
registers and then it's left to isel to fold memory operands.

In order to LICM intrinsics directly reading memory, we require that no stores
are in the loop (LICM) or that the folded load accesses constant memory
(MachineLICM).  When neither is the case we fail to hoist a loop-invariant
broadcast.

We can work around this limitation if we expose the load as a regular load and
then just implement the broadcast using the vector initializer syntax.  This
exposes the load to LICM and other optimizations.

At the IR level this is translated into a series of insertelements.  The
sequence is already recognized as a broadcast so there is no impact on the
quality of codegen.

_mm256_broadcast_pd and _mm256_broadcast_ps are not updated by this patch
because right now we lack the DAG-combiner smartness to recover the broadcast
instructions.  This will be tackled in a follow-on.

There will be completing changes on the LLVM side to remove the LLVM
intrinsics and to auto-upgrade bitcode files.

Add a test that we don't store stale modtime in modules

The change from r209195 turned out to be important to avoid saving stale
modification time/expected size information in a module file when there
are 3 or more modules in a dependency chain and the bottom one is
rebuilt. So add a test for that.
