09a5f4aaff Correctly set rpath on Mac OS X for executable tools. Note that I am not certain this is the best fix; the code immediately above looks confused, as it first checks to see if we are NOT on Darwin and then checks the Darwin version number. This fix allows c-index-test (in Clang) to run outside of running the regression test suite. I would appreciate if someone reviewed this.

2b2265a9c5 Fix PR7647, handling the case when 'To' ends up being
mutated by recursive simplification.  This also enhances
ReplaceAndSimplifyAllUses to actually do a real RAUW
at the end of it, which updates any value handles
pointing to "From" to start pointing to "To".  This
seems useful for debug info and random other VH users.

63cfa4b8e0 make various clients of ReplaceAndSimplifyAllUses tolerate
it *changing* the things it replaces, not just causing them
to drop to null.  There is no functionality change yet, but 
this is required for a subsequent patch.

491e6e24f7 Use std::vector instead of a hard-coded array. The length of that array could
get *very* large, but we only need it to be the size of the number of pregs.

27e348cfa5 Remove restriction on NEON alignment values. Some of the NEON ld/st
instructions use different values (e.g., 2-byte or 4-byte alignment).
Also fix ARMInstPrinter to print these alignments as bits instead of bytes.

e3aafe4988 Use TargetOpcode::COPY instead of X86-native register copy instructions when

07ef07c202 Make the order in which variables are described in debug information
independent of the order that isel happens to visit the dbg_declare
intrinsics. This fixes a bug in which the formal arguments were
being printed in reverse order, now that fast isel is going bottom up.

1f4fed20a5 Remove some broken code to check the DISABLE_EDIS flag (edis is now in the
DIRS list, so it does no good to filter it from PARALLEL_DIRS), and replace
it with a check to disable building the shared library version of edis when
the flag is set.  Disabling it entirely does not work because MC uses it now.

5de6c42ebd Extend SimplifyCFG's common-destination folding heuristic to allow a single
"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).

e2d1ecbe70 Improve 64-subtraction of immediates when parts of the immediate can fit
in the literal field of an instruction. E.g.,
long long foo(long long a) {
  return a - 734439407618LL;
}

f6478f489d Fix for PR7193 was overly conservative. The only case where sibcall callee
address cannot be allocated a register is in 32-bit mode where the first
three arguments are marked inreg. In that case EAX, EDX, and ECX will be
used for argument passing.

This fixes PR7610.
