d6f16587ab Sprinkle some PrettyStackEntry magic into the passmanager. With this, we now
get nice and happy stack traces when we crash in an optimizer or codegen.  For
example, an abort put in UnswitchLoops now looks like this:

Stack dump:
0.	Program arguments: clang pr3399.c -S -O3 
1.	<eof> parser at end of file
2.	per-module optimization passes
3.	Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4.	Running pass 'Loop Pass Manager' on function '@foo'
5.	Running pass 'Unswitch loops' on basic block '%for.inc'
Abort

35033a5876 Add a new 'AddSignalHandler' function to Signals.h that allows
arbitrary functions to be run when a crash happens.  Delete 
RemoveDirectoryOnSignal as it is dead and has never had clients.

Change PrintStackTraceOnErrorSignal to be implemented in terms of
AddSignalHandler.

I updated the Win32 versions of these APIs, but can't test them.
If there are any problems, I'd be happy to fix them as well.

c23b8719ef Give sentinel traits the right to determine the policy where the sentinel is kept.
This should result in less indirect memory accesses, less dead writes and tighter code.

c7f6b8c5d4 "Ghostify" embedded sentinels. This is a real win in all cases
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

160ae86936 Temporarily revert 65975, which breaks the llvm-gcc build.
While the patch is clearly correct in itself, it's become
apparent other places are assuming debug intrinsics are
marked as touching memory...this needs more testing.

95e2aa8967 Move code from Main.cpp to the include dir.

me some strange EH-related error anyway).

f188178a2f Reorganize llvmc code.
Move the code from 'llvmc/driver' into a new CompilerDriver library, and change
the build system accordingly. Makes it easier for projects using LLVM to build
their own llvmc-based drivers.

Tested with objdir != srcdir.

be a win, since almost every interesting function has at least one Argument.

abd6f28a74 Reuse a technique (pioneered for BasicBlocks) of superposing ilist with
its sentinel. This is quite a win when a function really has a basic block.                  
When the function is just a declaration (and stays so) the old way did not
allocate a sentinel. So this change is most beneficial when the ratio of
function definition to declaration is high. I.e. linkers etc. Incidentally  
these are the most resource demanding applications, so I expect that the
reduced malloc traffic, locality and space savings outweigh the cost of
addition of two pointers to Function.

The ones marked with an X have not been implemented since local dynamic is not implemented.
