8189d40a8d Fix libLTO by #include'ing the initializers for all targets and all asm 
printers.

While I'm here, alphabetize.

cbad586240 <rdar://problem/6940611> libLTO.dylib needs to let linker specify path to assembler 
Add lto_codegen_set_assembler_path() API which allows the linker to specify the
path to the assembler tool to run.  When assembler is used (instead of compiler)
different command line options are used.
Add LTO_API_VERSION #define so clients (linkers) can conditionalize use of new APIs.

e0f0e0be1c Change LTO to run the global opt pass twice. 
- This matches llvm-ld.

It took a bit of archeology to figure out what the right thing to do was
(whether this was intentionally added or intentionally removed). My final
conclusion is that Chris added this intentionally here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=16913
but the changes weren't propogated to llvm-ld until here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=34058
which was after lto.cpp had been cloned off (of llvm-ld), here:
  http://llvm.org/viewvc/llvm-project?view=rev&revision=29494

From the commit message, it looks like the motivation for running global opt
again is because we ran it prior to inlining. Based on that I updated the
comment and also only run the pass if we actually ran the inliner.

Chris, please review.

006a034828 Add createStandardLTOPasses to StandardPasses.h, and move lto and llvm-ld over. 
- I know it sounds crazy, but I think all the pass lists are now coalesced into
   StandardPasses.h.

195bea3498 Allow a user of libLTO to specify the full pathname of the gcc executable to 
run when assembling.

Wire this up to the gold plugin. You can now pass --plugin-opt gcc=/foo/bar/gcc
and it will run that gcc instead of looking for it on the path.

98a366d547 Instead of passing in an unsigned value for the optimization level, use an enum, 
which better identifies what the optimization is doing. And is more flexible for
future uses.

13319ceffd The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF. 
Add support for two additional DWARF attributes to encode Objective-C runtime version number.
