3112581441 Arithmetic instructions don't set EFLAGS bits OF and CF bits 
the same say the "test" instruction does in overflow cases,
so eliminating the test is only safe when those bits aren't
needed, as is the case for COND_E and COND_NE, or if it
can be proven that no overflow will occur. For now, just
restrict the optimization to COND_E and COND_NE and don't
do any overflow analysis.

fc5940d2a0 While thinking about the one-definition-rule and trying 
to find a tiny mouse hole to squeeze through, it struck
me that globals without a name can be considered internal
since they can't be referenced from outside the current
module.  This patch makes GlobalOpt give them internal
linkage.  Also done for aliases even though they always
have names, since in my opinion anonymous aliases should
be allowed for consistency with global variables and
functions.  So if that happens one day, this code is ready!

d6f16587ab Sprinkle some PrettyStackEntry magic into the passmanager. With this, we now 
get nice and happy stack traces when we crash in an optimizer or codegen.  For
example, an abort put in UnswitchLoops now looks like this:

Stack dump:
0.	Program arguments: clang pr3399.c -S -O3 
1.	<eof> parser at end of file
2.	per-module optimization passes
3.	Running pass 'CallGraph Pass Manager' on module 'pr3399.c'.
4.	Running pass 'Loop Pass Manager' on function '@foo'
5.	Running pass 'Unswitch loops' on basic block '%for.inc'
Abort

16e8eda4b8 Fix ScheduleDAGRRList::CopyAndMoveSuccessors' handling of nodes 
with multiple chain operands. This can occur when the scheduler
has added chain operands to a node that already has a chain
operand, in order to handle physical register dependencies.

in r66058.

46c95bbe06 Fix a parallel make race condition by swapping the order of -I directories. 
The .cmi files are generated in $(ObjDir) and then copied to $(OcamlDir).
The ocamldep output references the .cmi files in $(ObjDir), so make kicks
off a dependent compile as soon as the local copy is generated.  If the
copy to $(OcamlDir) is not complete at that point, the compiler will read
the partially copied file and complain about a "Corrupted compiled
interface".  Searching $(ObjDir) first avoids this.

5049600672 GlobalOpt only process non constant local GVs while optimizing global vars. 
If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B.

In other words, debug info should not interfere in removal of unused GV.
