a3f99f9033 First patch in the direction of splitting MachineCodeEmitter in two subclasses: 
JITCodeEmitter and ObjectCodeEmitter. No functional changes yet. Patch by Aaron Gray



git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72631 91177308-0d34-0410-b5e6-96231b3b80d8

d6b7a242d3 Add support to the JIT for true non-lazy operation. When a call to a function 
that has not been JIT'd yet, the callee is put on a list of pending functions
to JIT.  The call is directed through a stub, which is updated with the address
of the function after it has been JIT'd.  A new interface for allocating and
updating empty stubs is provided.

Add support for removing the ModuleProvider the JIT was created with, which
would otherwise invalidate the JIT's PassManager, which is initialized with the
ModuleProvider's Module.

Add support under a new ExecutionEngine flag for emitting the infomration 
necessary to update Function and GlobalVariable stubs after JITing them, by
recording the address of the stub and the name of the GlobalValue.  This allows
code to be copied from one address space to another, where libraries may live
at different virtual addresses, and have the stubs updated with their new
correct target addresses.

46fa139e26 Support for allocation of TLS variables in the JIT. Allocation of a global 
variable is moved to the execution engine. The JIT calls the TargetJITInfo
to allocate thread local storage. Currently, only linux/x86 knows how to
allocate thread local global variables.

ec90cd1bf8 Disable cfi directives for now, darwin does't support them. 
These should probably be something like:

  CFI(".cfi_def_cfa_offset 16\n")

where CFI is defined to a noop on darwin and other platforms
that don't support those directives.

  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.
