Currently private copies of captured variables have default alignment. Patch makes private variables to have same alignment as original variables.

Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least.
Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record.

Given a reference to a pointer to member whose class's inheritance model
is unspecified, make sure we come up with an inheritance model in
plausible places.  One place we were missing involved LValue to RValue
conversion, another involved unary type traits.

This flag causes the compiler to emit bit set entries for functions as well
as runtime bitset checks at indirect call sites. Depends on the new function
bitset mechanism.

This reapply a variant commit r247179 after post-commit review from
D.Blaikie.
Hopefully I got it right this time: lifetime of initializer list ends
as with any expression, which make invalid the pattern:

ArrayRef<int> Arr = { 1, 2, 3, 4};

Just like StringRef, ArrayRef shouldn't be used to initialize local
variable but only as function argument.

We know that a reference can always be dereferenced.  However, we don't
always know the number of bytes if the reference's pointee type is
incomplete.  This case was correctly handled but we didn't consider the
case where the type is complete but we cannot calculate its size for ABI
specific reasons.  In this specific case, a member pointer's size is
available only under certain conditions.

This fixes PR24703.

Summary:
Currently clang provides no general way to generate nontemporal loads/stores.
There are some architecture specific builtins for doing so (e.g. in x86), but
there is no way to generate non-temporal store on, e.g. AArch64. This patch adds
generic builtins which are expanded to a simple store with '!nontemporal'
attribute in IR.

Revert "[Static Analyzer] BugReporter.cpp:2869: Assertion failed: !RemainingNodes.empty() && "No error node found in the trimmed graph""

This is making our internal build bot fail because it results in extra warnings being
emitted past what should be sink nodes. (There is actually an example of this in the
updated malloc.c test in the reverted commit.)

I'm working on a patch to fix the original issue by adding a new checker API to explicitly
create error nodes. This API will ensure that error nodes are always tagged in order to
prevent them from being reclaimed.

This reverts commit r246188.
