33f7ecabd4 Temporarily stop recovering resources in CrashRecoveryContext while I investigate further why this works on my machine and not on others.

371ad9a265 Rework CrashRecoveryContextCleanup to provide a simpler way to create cleanup objects, and provide a new cleanup for 
decrementing reference counts of objects with intrusive reference counts.

e19f7261d5 Hook up the MCJIT to the RuntimeDyld library. 
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.

fc9e8a04c3 Dont emit 'DBG_VALUE %noreg, ...' to terminate user variable ranges. 
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.

9ad8d572e9 Library-ize the dyld components of llvm-rtdyld. 
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.

9adf1c9edd A WIP commit of the InstAlias printing cleanup. This code will soon replace the 
code below it. Even though it looks very similar, it will match more precisely
and geneate better functions in the long run.

This is a helper class that will make it easier to say which InstAliases can be
printed and which cannot (because of ambiguity).

a2eec46242 We need to pass the TargetMachine object to the InstPrinter if we are printing 
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.

dd8cb156c1 Avoid initializing posix_spawn_file_actions_t if not used. 
- glibc falls back to fork+exec if a file actions object is present.
- On BSDs this saves a malloc.
