ad7f61c279 Reapply 68847. 
Now debug_inlined section is covered by TAI->doesDwarfUsesInlineInfoSection(), which is false by default.

ac11c8d30f Revert r68847. It breaks the build on non-Darwin targets, with this message 
from the assembler:

Error: unknown pseudo-op: `.debug_inlined'

6f907173e0 Keep track of inlined functions and their locations. This information is collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) 
Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions. See DwarfWriter.cpp for more information on structure of debug_inlined section.

067c48f7a6 Linux wants the FDE initial location and address range to be forced to 32-bit. 
Darwin doesn't. Make this optional for platforms.

7593f0004f Fix bug 3202. 
The EH_frame and .eh symbols are now private, except for darwin9 and earlier.
The patch also fixes the definition of PrivateGlobalPrefix on pcc linux.

1ed08a58d1 Fix logic for not emitting no-dead-strip for some 
objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).
