Simplify JIT unit test #ifdefs

Several platforms need to disable all old-JIT unit tests, since they only
support the new MCJIT.  This currently done via #ifdef'ing out those tests
in the ExecutionEngine/JIT/*.cpp files.  As those #ifdef's have grown
historically, we now have a number of repeated directives which -in total-
cover nearly the whole file, but leave a couple of helper functions out.
When building the tests with clang itself, those helper functions now
cause spurious "unused function" warnings.

To fix those warnings, and also to remove the duplicate #ifdef conditions
and make it easier to disable the tests for a new target, this patch
consolidates the #ifdefs into a single one per file, which covers all
the tests including all helper routines.

Tested on PowerPC and SystemZ.

[SystemZ] Define DWARF encoding

This is another patch in preparation for adding the SystemZ target.
It defines the appropriate values for DWARF encodings; the intent
is to be compatible with what GCC currently does on the target.

[SystemZ] Add back end

This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target.  Note that at this point, the target
cannot yet be built since the configure bits are missing.  Those
will be provided shortly by a follow-on patch.

This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov.  Thanks to all reviewers!

[SystemZ] Set up JIT/MCJIT test cases

This patch adds the necessary configuration bits and #ifdef's to set up
the JIT/MCJIT test cases for SystemZ.  Like other recent targets, we do
fully support MCJIT, but do not support the old JIT at all.  Set up the
lit config files accordingly, and disable old-JIT unit tests.

[SystemZ] Add configure bits

This patch wires up the SystemZ target in configure, so that it can now be

AArch64: use MCJIT by default and enable related tests.

This just enables some testing I'd missed after implementing MCJIT
support.

Provide InstCombines for the following 3 cases:
A * (1 - (uitofp i1 C)) -> select C, 0, A
B * (uitofp i1 C) -> select C, B, 0
select C, 0, A + select C, B, 0 -> select C, B, A

These come up in code that has been hand-optimized from a select to a linear blend, 
on platforms where that may have mattered. We want to undo such changes 
with the following transform:
A*(1 - uitofp i1 C) + B*(uitofp i1 C) -> select C, A, B

[SystemZ] Update non-pic DWARF encodings

As pointed out by Rafael Espindola, we should match the DWARF encodings
produced by GCC in both pic and non-pic modes.  This was not the case
for the non-pic case.

This patch changes all DWARF encodings to DW_EH_PE_absptr for the
non-pic case, just like GCC does.  The test case is updated to check
for both variants.
