Allow SROA to split up an array of vectors into multiple vectors, even when the vectors are dynamically indexed

linkonce linkage. For example, it is not valid to add unnamed_addr.

This also fixes a crash in g++.dg/opt/static5.C.

This probably mostly shows up in bugpoint-generated code.

We only do very limited physreg coalescing now, but we still merge
virtual registers into reserved registers.

Patch extracted from a larger one by the PaX team. I added the testcases
and tightened error handling a bit.

Thanks to Charles Davis for the testcase that uncovered this can of worms.

Recommit r158407: Allow SROA to look at a vector type and see if the offset is out of range to be replaced with a scalar access.  Now with additional fix and test for indexing into a vector inside a struct

not.

Can someone with more knowledge of this please look at other entries
to see if others need moved.
