Add a JITEventListener interface that gets called back when a new function is
emitted or the machine code for a function is freed.  Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change.  I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.

This increases the maximum for MVT::LAST_VALUETYPE

This change doubles the allowable value for MVT::LAST_VALUETYPE. It does
this by doing several things.

1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a
value of 64.  This value contains the current maximum for the
MVT::LAST_VALUETYPE.

2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses
now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE"

3. Changes the dimension of the ValueTypeActions from 2 elements to four
elements and adds comments ahead of the declaration indicating the it is
"(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2".  This at least lets us find
what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets
changed.

4. Adds initializers for the new elements of ValueTypeActions.

This does NOT add any types in MVT. That would be done separately.

This doubles the size of ValueTypeActions from 64 bits to 128 bits and
gives us the freedom to add more types for AVX.

Guard the listeners list.  Unfortunately, this requires a real static rather
than a managed static because other managed statics can (and do) access this
list in their destructors.  Yes, I know it's horrible.

Provide InitializeAllTargets and InitializeNativeTarget functions in the
C bindings.  Change all the backend "Initialize" functions to have C linkage.
Change the "llvm/Config/Targets.def" header to use C-style comments to avoid
compile warnings.

It is not a good idea to have data member's name match argument's name. In fact, it is a simple receipe to waste an hour or so.

Use atomic operations when accessing statistics, and make the lazy initialization of statistics actually threadsafe.

Add atomic multiply and divide operations, built on top of CompareAndSwap.

Make timers threadsafe again.  This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic),
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.

Make llvmc work again.

Chris recently broke llvmc with his Makefile changes (r75379). That patch made
the global change .o -> .a, which caused built-in llvmc plugins to stop working
since plugin initialization in llvmc is based on static variables not referenced
from the main executable. This patch implements auto-generated forced references
to the plugin libraries.
