71b7f646de Move the code that adds the DeadMachineInstructionElimPass from 
target-independent code to target-specific code. This prevents it
from running on targets that aren't using fast-isel.

In addition to saving compile time, this addresses the problem
that not all targets are prepared for it. In order to use this
pass, all instructions must declare all their fixed uses and
defs of physical registers.

46fa139e26 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.

4047f4a0b4 Fix translateX86CC: if SetCCOpcode is SETULE and 
LHS is a foldable load, then LHS and RHS are swapped
and SetCCOpcode is changed to SETUGT.  But the later
code is expecting operands to be the wrong way round
for SETUGT, but they are not in this case, resulting
in an inverted compare.  The solution is to move the
load normalization before the correction for SETUGT.
This bug was tickled by LegalizeTypes which happened
to legalize the testcase slightly differently to
LegalizeDAG.

394f0441e0 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.
