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.

d519223908 hoist MCContext/MCStreamer up to AsmPrinter since we're going to start creating 
MCSections soon instead of Section for all targets, and we need something to
own them.

34d4b90554 Many of Daniel's fixes. 
I'm returning the number of bytes actually copied so that the client has some
warning when it reads past the end of the buffer.

I'm keeping the distinction between getByte() and getBytes() for now for
subclasses that use functions like ptrace() on Linux and only have a restricted
interface.  This makes their implementation easier, and subclasses can always
write a one-line implementation of readByte() that uses their custom 
readBytes().

0f4d60ca90 untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create a 
'unnamed' bss section, but some impls would want a named one.  Since
they don't have consistent behavior, just make each target do their
own thing, instead of doing something "sortof common" then having
targets change immutable objects later.

8e840e942e Use the RHS length instead of the LHS length. They are both the same, 
but this ends up compiling code like this:

int foo(const StringRef &R) {
  return R == "food";
}

to use a constant sized memcmp instead of a variable memcmp.

b3d6d59c10 Rearrange all the SectionKinds and structure them into a hierarchical 
group instead of a bunch of random unrelated ideas.  Provide predicates
to categorize a SectionKind into a group, and use them instead of 
getKind() throughout the code.

This also renames a ton of SectionKinds to be more consistent and
evocative, and adds a huge number of comments on the enums so that
I will hopefully be able to remember how this stuff works long from
now.
