David Blaikie f68e809c5e Fix PR12378: provide conversion warnings on default args of function templates
Apparently we weren't checking default arguments when they were instantiated.
This adds the check, fixes the lack of instantiation caching (which seems like
it was mostly implemented but just missed the last step), and avoids
implementing non-dependent default args (for non-dependent parameter types) as
uninstantiated default arguments (so that we don't warn once for every
instantiation when it's not instantiation dependent).

Derek Schuff b051adf263 Fix fastcc structure return with fast-isel on x86-32
On x86-32, structure return via sret lets the callee pop the hidden
pointer argument off the stack, which the caller then re-pushes.
However if the calling convention is fastcc, then a register is used
instead, and the caller should not adjust the stack. This is
implemented with a check of IsTailCallConvention
X86TargetLowering::LowerCall but is now checked properly in
X86FastISel::DoSelectCall.

(this time, actually commit what was reviewed!)

Bob Wilson 9245c93656 Don't introduce illegal types when creating vmull operations. <rdar://11324364>
ARM BUILD_VECTORs created after type legalization cannot use i8 or i16
operands, since those types are not legal.  Instead use i32 operands, which
will be implicitly truncated by the BUILD_VECTOR to match the element type.

Eli Bendersky b92e1cf636 It doesn't make sense to move symbol relocations to section relocations when
relocations are resolved.  It's much more reasonable to do this decision when
relocations are just being added - we have all the information at that point.

Also a bit of renaming and extra comments to clarify extensions.

Bill Wendling bf4b9afbeb Second attempt at PR12573:
Allow the "SplitCriticalEdge" function to split the edge to a landing pad. If
the pass is *sure* that it thinks it knows what it's doing, then it may go ahead
and specify that the landing pad can have its critical edge split. The loop
unswitch pass is one of these passes. It will split the critical edges of all
edges coming from a loop to a landing pad not within the loop. Doing so will
retain important loop analysis information, such as loop simplify.

David Blaikie 2d7c57ec1d Remove the ref/value inconsistency in filter_decl_iterator.
filter_decl_iterator had a weird mismatch where both op* and op-> returned T*
making it difficult to generalize this filtering behavior into a reusable
library of any kind.

This change errs on the side of value, making op-> return T* and op* return
T&.

Julien Lerouge 4a5b444371 Currently __builtin_annotation() only annotates an i32.
i32 __builtin_annotation(i32, string);

Applying it to i64 (e.g., long long) generates the following IR.

        trunc i64 {{.*}} to i32
        call i32 @llvm.annotation.i32
        zext i32 {{.*}} to i64

The redundant truncation and extension make the result difficult to use.

This patch makes __builtin_annotation() generic.

        type __builtin_annotation(type, string);

For the i64 example, it simplifies the generated IR to:

        call i64 @llvm.annotation.i64
