GCC would put weak zero initialized mutable data in the .bss section,
we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' 
section.  Fixing this will allow simplifications next up.

simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

Fix r93758. Use isel patterns instead of c++ selection code to select rbit and make sure we pick different instructions for ARM vs. Thumb2.

cursor itself. In particular, for references this returns the source
range of the reference rather than the source range of the thing it
refers to.

Switch c-index-test from clang_getDeclExtent (which will eventually be
deprecated and removed) over to clang_getCursorExtent. The source
ranges we print for references now make sense; fix up the tests
appropriately.

to break any functionality, but will introduce
cases where -g affects the generated code.  I'll
be fixing that.
