d7aad34bcb Fix a tblgen subtargetemitter bug, for future Swift support.
This fixes some of the ridiculously complex code for optimizing the
machine model tables that are shared among all processors of a given
target. A9 and Swift both use the "special" feature that maps old
itinerary classes to new machine model defs. They map different
overlapping subsets of instructions, which wasn't handled correctly.

032d62487c PR15662: Optimized debug info produces out of order function parameters
When a function is inlined we lazily construct the variables
representing the function's parameters. After that, we add any remaining
unused parameters.

If the function doesn't use all the parameters, or uses them out of
order, then the DWARF would produce them in that order, producing a
parameter order that doesn't match the source.

This fix causes us to always keep the arg variables at the start of the
variable list & in the original order from the source.

5a57dbef33 IndVarSimplify: check if loop invariant expansion can trap
IndVarSimplify is willing to move divide instructions outside of their
loop bodies if they are invariant of the loop.  However, it may not be
safe to expand them if we do not know if they can trap.

Instead, check to see if it is not safe to expand the instruction and
skip the expansion.

This fixes PR16041.

babae05237 Second part of pr16069
The problem this time seems to be a thinko. We were assuming that in the CFG

A
| \
|  B
| /
C

speculating the basic block B would cause only the phi value for the B->C edge
to be speculated. That is not true, the phi's are semantically in the edges, so
if the A->B->C path is taken, any code needed for A->C is not executed and we
have to consider it too when deciding to speculate B.

b30718af1a IEEE-754R 5.7.2 General Operations is* operations (except for isCanonical).
Specifically the following work was done:

1. If the operation was not implemented, I implemented it.

2. If the operation was already implemented, I just moved its location
in the APFloat header into the IEEE-754R 5.7.2 section. If the name was
incorrect, I put in a comment giving the true IEEE-754R name.

Also unittests have been added for all of the functions which did not
already have a unittest.

45c7544339 Fix a defect in code-layout pass, improving Benchmarks/Olden/em3d/em3d by about 30%
(4.58s vs 3.2s on an oldish Mac Tower). 

  The corresponding src is excerpted bellow. The lopp accounts for about 90% of execution time.
  --------------------
    cat -n test-suite/MultiSource/Benchmarks/Olden/em3d/make_graph.c
     90 
     91         for (k=0; k<j; k++)
     92           if (other_node == cur_node->to_nodes[k]) break;

  The defective layout is sketched bellow, where the two branches need to swap.
  ------------------------------------------------------------------------
      L:
         ...
      if (cond) goto out-of-loop
      goto L

  While this code sequence is defective, I don't understand why it incurs 1/3 of 
execution time. CPU-event-profiling indicates the poor laoyout dose not increase
in br-misprediction; it dosen't increase stall cycle at all, and it dosen't 
prevent the CPU detect the loop (i.e. Loop-Stream-Detector seems to be working fine
as well)... 

   The root cause of the problem is that the layout pass calls AnalyzeBranch() 
with basic-block which is not updated to reflect its current layout.

3931bdb788 SimplifyCFG: Do not transform PHI to select if doing so would be unsafe
PR16069 is an interesting case where an incoming value to a PHI is a
trap value while also being a 'ConstantExpr'.

We do not consider this case when performing the 'HoistThenElseCodeToIf'
optimization.

Instead, make our modifications more conservative if we detect that we
cannot transform the PHI to a select.
