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.

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

the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
indirect branch).  Instead of '1', it should be specified as '?', because GPR
only specifies the register class, which includes both hi-and-lo registers.

"On ARMv6T2 this turns cttz into rbit, clz instead of the 4 instruction
 sequence it is now."

- Default to using 4-bytes for the LSDA pointer encoding to agree with the
  encoded value in the CIE.

expected output for gcc's Neon tests.

doing it textually (in x86)

remove it and change all the code that prints MCSymbols to use

stop the CBE from using Mangler::appendMangledName, which is a private function, it is mangling types, which don't matter how they are done.

to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

adding an "i" to the suffix, indicating that the elements are integers, is
accepted but not part of the standard syntax.  This helps us pass a few more
of the Neon tests from gcc.

The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.
