The RegionInfo pass detects single entry single exit regions in a function,
where a region is defined as any subgraph that is connected to the remaining
graph at only two spots.
Furthermore an hierarchical region tree is built.
Use it by calling "opt -regions analyze" or "opt -view-regions".

Patch by Olivier Meurant!

for lowering without sse2.  Add a couple of new testcases.

Fixes a few libgomp tests and latent bugs.  Remove a few todos.

Fix constant island pass's handling of tBR_JTr. The offset of the instruction does not have to be 4-byte aligned. Rather, it's the offset + 2 that must be aligned since the instruction expands into:
        mov     pc, r1
        .align  2
LJTI0_0_0:
        .long    LBB0_14

This fixes rdar://8213383. No test case since it's not possible to come up with a suitable small one.

described in their SSE forms, but are described in AVX)

Add INSTANTIATE_AG_PASS, which combines RegisterPass<> with RegisterAnalysisGroup<> for pass registration.

"needsexactsize") was sent for consideration to llvmdev.

Add missing AVX convert instructions. Those instructions are not described in their SSE forms (although they exist), but add the AVX forms anyway, so the assembler can benefit from it
