c70ddad2b7 Partially in response to PR926: insert the newly created machine basic
blocks into the basic block list when lowering the switch inst. into a
binary tree of if-then statements. This allows the "visitSwitchCase" func
to allow for fall-through behavior.

002e499650 It is OK to remove extra cast if operation is EQ/NE even though source
and destination sign may not match but other conditions are met.

b1c8802407 Fixed mingw\cygwin linkonce linkage once again.
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.

ffddf6ba1c Enable deleting branches to successor blocks. With the previous patches,
branch folding can now compile stuff like this:

void foo(int W, int X, int Y, int Z) {
  if (W & 1) {
    for (; X;--X) bar();
  } else if (W & 2) {
    for (; Y;--Y) bar();
  } else if (W & 4) {
    for (; Z;--Z) bar();
  } else if (W & 8) {
    for (; W;--W) bar();
  }

  if (W) {
    bar();
  }
}

contrived testcase where loops exits all end up merging together.  To have
the loop merges be:

...
        cmplw cr0, r30, r27
        bne cr0, LBB1_14        ;bb38
LBB1_16:        ;cond_next48.loopexit
        mr r27, r29
LBB1_20:        ;cond_next48
        cmplwi cr0, r27, 0
        beq cr0, LBB1_22        ;UnifiedReturnBlock
...

instead of:


...
        cmplw cr0, r30, r27
        bne cr0, LBB1_14        ;bb38
LBB1_16:        ;cond_next48.loopexit
        mr r27, r29
        b LBB1_20       ;cond_next48
LBB1_17:        ;cond_next48.loopexit1
        b LBB1_20       ;cond_next48
LBB1_18:        ;cond_next48.loopexit2
        b LBB1_20       ;cond_next48
LBB1_19:        ;cond_next48.loopexit3
LBB1_20:        ;cond_next48
        cmplwi cr0, r27, 0
        beq cr0, LBB1_22        ;UnifiedReturnBlock
