Update CodeGen regression tests with marker at first line telling it's
auto-generated by the script, under PowerPC directory. For some reason,
these tests are generated but manually written, which makes things
unclear when someone's change affecting them.
However, some tests only show simple change after re-generated, like
extra blank lines, disappearing '.localentry', etc. Besides, some tests
are generated but added checks for debug output. This commit doesn't try
updating them.
As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.
The MIR printer prints the IR name of a MBB only for block definitions.

This patch adds on to the exploitation added by https://reviews.llvm.org/D33510.
This now catches build vector nodes where the inputs are coming from sign
extended vector extract elements where the indices used by the vector extract
are not correct. We can still use the new hardware instructions by adding a
shuffle to move the elements to the correct indices. I introduced a new PPCISD
node here because adding a vector_shuffle and changing the elements of the
vector_extracts was getting undone by another DAG combine.
