Instead, have a DataLayoutPass that holds one. This will allow parts of LLVM
don't don't handle passes to also use DataLayout.

After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

r201608 made llvm corretly handle private globals with MachO. r201622 fixed
a bug in it and r201624 and r201625 were changes for using private linkage,
assuming that llvm would do the right thing.
They all got reverted because r201608 introduced a crash in LTO. This patch
includes a fix for that. The issue was that TargetLoweringObjectFile now has
to be initialized before we can mangle names of private globals. This is
trivially true during the normal codegen pipeline (the asm printer does it),
but LTO has to do it manually.

Since r201608 got reverted, it is not safe to use private linkage in these cases
until it is committed back.

This patch places class definitions in implementation files into anonymous
namespaces to prevent weak vtables. This eliminates the need of providing an
out-of-line definition to pin the vtable explicitly to the file.

This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file. The memory leaks in this version have been fixed. Thanks
Alexey for pointing them out.

This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
Base *foo = new Child();
delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

The old jit always uses DW_EH_PE_absptr, but MCJIT can use other encodings.
This is in preparation for adding EH support to MCJIT, but not directly
related, so I am committing it first.

This was always part of the VMCore library out of necessity -- it deals
entirely in the IR. The .cpp file in fact was already part of the VMCore
library. This is just a mechanical move.
I've tried to go through and re-apply the coding standard's preferred
header sort, but at 40-ish files, I may have gotten some wrong. Please
let me know if so.
I'll be committing the corresponding updates to Clang and Polly, and
Duncan has DragonEgg.
Thanks to Bill and Eric for giving the green light for this bit of cleanup.

llvm-ld is no longer useful and causes confusion and so it is being removed.
* Does not work very well on Windows because it must call a gcc like driver to
assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
ld, or fully replaced by Clang.
I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

Also conducted some reformatting. As the LLVM coding standard doc does not
seem to touch on how to align function arguments, and format code longer than
80 cols in general, the confusion persists. There is the golden rule, but as
this code has gone through several styles to deal with this, the golden rule
seems to be ignored. The latest reformatting effort tries to match the other
source files as much as possible.

infrastructure. As this makes the demo no longer a demo, and especially not a
demo on how to use the llvm exception mechanism, this hack will shortly be
changed to use the new 3.0 exception infrastructure. However for the time being
this demo is an example on how to use the AutoUpgrade
UpgradeExceptionHandling(...) function on < 3.0 exception handling code.
