Support argument passing simple, common, prototypes directly. More
complicated scenarios will require building up a stub function, which the
MC-JIT isn't set up to handle yet.

Add Intercept.cpp, which is just a copy from ExecutionEngine/JIT for now,
to handle looking looking up external symbol names. This probably more
properly belongs as part of RuntimeDyld. It'll migrate there as things
flesh out more fully.

Properly initialize all fields in CrashReporterCleanupContext.  This caused the buildbot failure earlier.

Temporarily stop recovering resources in CrashRecoveryContext while I investigate further why this works on my machine and not on others.

Lots of cleanup to make the interfaces prettier, use the JITMemoryManager,
handle multiple functions and modules, etc.. This gets far enough that
the MCJIT compiles and runs code, though.

This is likely to fix the segfault in llvm-gcc-x86_64-darwin10-cross-mingw32.

These ranges get completely jumbled by the post-ra scheduler, and it is not
really reasonable to expect it to make sense of them.

Instead, teach DwarfDebug to notice when user variables in registers are
clobbered, and terminate the ranges there.

outside of the current basic block. This fixes PR9500, rdar://9156159.

Add support for Thumb interworking addresses for symbol offsets that get constant folded very early.
This fixes SPASS with -integrated-as.  <rdar://problem/9165399>

Move the dynamic linking functionality of the llvm-rtdyld program into an
ExecutionEngine support library. Update llvm-rtdyld to just load an object
file into memory, use the library to process it, then run the _main()
function, if one is found.

Provide a means for CrashRecovery clients to determine if code is currently running while crash recovery cleanups are being processed.

the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

As suggested by Nick Lewycky, ignore debugging intrinsics when trying to decide whether a destructor is empty or not.

gun as does. This makes it a lot easier to compare the output of both
as the addresses are now a lot closer.

Add an optimization to GlobalOpt that eliminates calls to __cxa_atexit, if the function passed is empty.

- glibc falls back to fork+exec if a file actions object is present.
- On BSDs this saves a malloc.

splitting.
