273ff31e13 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.

b5378ea12e Use TargetOpcode::COPY instead of X86-native register copy instructions when 
lowering atomics. This will allow those copies to still be coalesced after
TII::isMoveInstr is removed.

336e8d7e7c 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.

8f70c3d97c 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.

e84178a0bd 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).

dedd974e7e 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.
