c5d6ef88ff Add a new hidden option to the interpreter to cause it to print 
out every volatile load and store.  This is useful for tracking 
down insane volatile memory bugs.

c8097f8c8c Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating 
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.

ef1aa7c9db Switch the PPC backend and target-independent JIT to use the libsystem 
InvalidateInstructionCache method instead of calling through
a hook on the JIT.  This is a host feature, not a target feature.

a JIT client to completely control symbol lookup with the LazyFunctionCreator
interface.

26bb02a23a Fix a couple issues with the JIT and multiple modules: 
1. The "JITState" object creates a PassManager with the ModuleProvider that the
   jit is created with.  If the ModuleProvider is removed and deleted, the
   PassManager is invalid.

2. The Global maps in the JIT were not invalidated with a ModuleProvider was 
   removed.  This could lead to a case where the Module would be freed, and a 
   new Module with Globals at the same addresses could return invalid results.

768b6f281e Add CommonLinkage; currently tentative definitions 
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both.  The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

5fdce98ebd Do not hold the JIT lock when materializing a function and verify if the 
function has already been codegen'd. This is required by the Java class loading
mechanism which executes Java code when materializing a function.
