6125b9e097 - More pre-split fixes: spill slot live interval computation bug; restore point bug. 
- If a def is spilt, remember its spill index to allow its reuse.

d735f403a0 Support for constant islands in the ARM JIT. 
Since the ARM constant pool handling supercedes the standard LLVM constant
pool entirely, the JIT emitter does not allocate space for the constants,
nor initialize the memory. The constant pool is considered part of the 
instruction stream.

Likewise, when resolving relocations into the constant pool, a hook into
the target back end is used to resolve from the constant ID# to the
address where the constant is stored.

For now, the support in the ARM emitter is limited to 32-bit integer. Future
patches will expand this to the full range of constants necessary.

93f9f0f718 Have TableGen emit setSubgraphColor calls under control of a -gen-debug 
flag.  Then in a debugger developers can set breakpoints at these calls
to see waht is about to be selected and what the resulting subgraph
looks like.  This really helps when debugging instruction selection.

3bcbccf563 For now, don't split live intervals around x87 stack register barriers. FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them.

ce30b5caf0 Support for allocation of TLS variables in the JIT. Allocation of a global

to allocate thread local storage. Currently, only linux/x86 knows how to
allocate thread local global variables.

c906d4938e Committing a good chunk of the pre-register allocation live interval splitting pass. It's handling simple cases and appear to do good things. Next: avoid splitting an interval multiple times; renumber registers when possible; record stack slot live intervals for coloring; rematerialize defs when possible.

5447f9679d Change create*Pass factory functions to return Pass* instead of 
LoopPass*.
 - Although less precise, this means they can be used in clients
   without RTTI (who would otherwise need to include LoopPass.h, which
   eventually includes things using dynamic_cast). This was the
   simplest solution that presented itself, but I am happy to use a
   better one if available.

112ac04abd fix a tricky bug in the JIT global variable emitter, that was triggered when JITing a variable independently of a function. This lead to sharing memory memory between functions and GVs thus changing the value of a GV could change the code in execution. more details on the ML.
