85a3632c7a fix PR4650: we only track sizes for certain objects, so only put something
into the mergable section if it is one of our special cases.  This could
obviously be improved, but this is the minimal fix and restores us to the
previous behavior.

84205d6042 remove some completely wrong code. 1 is never < 16. It turns out that GCC appears to put strings of any length into the ELF cstring equivalent, so just rip out the code.

c74586940a the apple "ld_classic" linker doesn't support .literal16 in 32-bit
mode, and "ld64" (the default linker) falls back to it in -static
mode.

55461787cc Rip all of the global variable lowering logic out of TargetAsmInfo. Since
it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.

Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.

This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
   pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
   CStringSection_.  Factor the code better.
5. fixes some bugs in string lowering on ELF targets.
