Begin adding AVX2 intrinsics. Necessitated increasing the number of bits used to store builtinID when serializing identifier table.

intrinsics to use "I" (ICE) markings.  Fix avxintrin.h to take them into 
account.

evaluator into constant initializer handling / IRGen. The practical consequence
of this is that the bitcast now lives in the constant's definition, rather than
in its uses.

The code in the constant expression evaluator was producing vectors of the wrong
type and size (and possibly of the wrong value for a big-endian int-to-vector
bitcast). We were getting away with this only because we don't yet support
constant-folding of any expressions which inspect vector values.

Make EmitAggregateCopy take an alignment argument.  Make EmitFinalDestCopy pass in the correct alignment when known.

The test includes a FIXME for a related case involving calls; it's a bit more complicated to fix because the RValue class doesn't keep track of alignment.

When we're passing a vector with an illegal type through memory on x86-64, use byval so we're sure the backend does the right thing.  Fixes va_arg with illegal vectors and an obscure ABI mismatch with __m64 vectors.

llvm-svn: 145652

Don't use a varargs convention for calls unprototyped functions where one of the arguments is an AVX vector.

llvm-svn: 145574

Correct the code generation for function arguments of vec3 types on x86_64 when they are greater than 128 bits. This was incorrectly coercing things like long3 into a double2.
Add test case.

Fix the meaning of an "empty" record for the case of a zero-length array.  Use isEmptyRecord for arguments on x86-32; there are structs of size 0 which don't count as empty.

A bunch of fixes to argument passing and va_arg on Darwin x86-32 for structures containing an SSE vector.

llvm-svn: 144961

Simplify code for returning a struct for Darwin x86-32 ABI.  Use a better type for a function returning a struct containing only a pointer.  Handle the edge case of a struct containing only a float or double plus some dead padding instead of asserting.

Fix the representation of wide strings in the AST and IR so that it uses the native representation of integers for the elements.  This fixes a bunch of nastiness involving
treating wide strings as a series of bytes.
