code generator would do something like this:

f64 = load f32 <anyext>, f32mem
v2f64 = insertelt undef, %0, 0
v2f64 = insertelt %1, 0.0, 1

into 

v2f64 = vzext_load f32mem

which on x86 is movsd, when you really wanted a cvtss2sd/movsd pair.

Eliminate x86.sse2.movs.d, x86.sse2.shuf.pd, x86.sse2.unpckh.pd, and x86.sse2.unpckl.pd intrinsics. These will be lowered into shuffles.

Remove x86.sse2.loadh.pd and x86.sse2.loadl.pd. These will be lowered into load and shuffle instructions.

Bug: rcpps can only folds a load if the address is 16-byte aligned. Fixed many 'ps' load folding patterns in X86InstrSSE.td which are missing the proper alignment checks.
Also fixed some 80 col. violations.

X86CodeEmitter should not set PIC style to None at initialization time. This will break codegen if relocation model is changed to PIC_ later.

Make use of vector load and store operations to implement memcpy, memmove, and memset. Currently only X86 target is taking advantage of these.

are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Instead of a vector load, shuffle and then extract an element. Load the element from address with an offset.
        pshufd $1, (%rdi), %xmm0
        movd %xmm0, %eax
=>
        movl 4(%rdi), %eax

Teach X86 a few more vsetcc patterns.  Custom lowering for unsupported ones is next.
