Rafael Espindola f8b27c41e8 Nuke the old JIT. 
I am sure we will be finding bits and pieces of dead code for years to
come, but this is a good start.

Thanks to Lang Hames for making MCJIT a good replacement!

NAKAMURA Takumi 23b702c8de [CMake] Update libdeps.

Filip Pizlo c95bd8d88f Stackmaps are used for OSR exits, which is a custom kind of unwinding. Hence, they 
should not be marked nounwind.

Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable 
sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind 
data for that matter), making deoptimization via stackmaps impossible.

This changes the stackmap intrinsic to be may-throw, adds a test for exactly the 
sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics.

Thanks to atrick and philipreames for reviewing this.

Rafael Espindola 72780ed996 Revert "Adding object caching support to MCJIT" 
This reverts commit 07f03923137a91e3cca5d7fc075a22f8c9baf33a.

Looks like it broke the valgrind bot:

Andrew Kaylor ab5ba51a6e Moving SectionMemoryManager into RuntimeDyld and adding unit tests for it. 
The SectionMemoryManager now supports (and requires) applying section-specific page permissions.  Clients using this memory manager must call either MCJIT::finalizeObject() or SectionMemoryManager::applyPermissions() before executing JITed code.

See r168718 for changes from the previous implementation.
