2. ((x&0xff)<<8)|((x&0xff00)>>8)|((x&0xff000000)>>8)|((x&0x00ff0000)<<8))
   => (rotl (bswap x) 16)

This allows us to eliminate most of the def : Pat patterns for ARM rev16
revsh instructions. It catches many more cases for ARM and x86.

ops.

This is a rewrite of the IV simplification algorithm used by
-disable-iv-rewrite. To avoid perturbing the default mode, I
temporarily split the driver and created SimplifyIVUsersNoRewrite. The
idea is to avoid doing opcode/pattern matching inside
IndVarSimplify. SCEV already does it. We want to optimize with the
full generality of SCEV, but optimize def-use chains top down on-demand rather
than rewriting the entire expression bottom-up. This was easy to do
for operations that SCEV can prove are identity function. So we're now
eliminating bitmasks and zero extends this way.

A result of this rewrite is that indvars -disable-iv-rewrite no longer
requires IVUsers.

while back.  By default its output will be less verbose than the
old examine-threads.c but adding the '-v' command line flag will
give all the information that examine-threads.c provided plus some.

Of note, this implementation can take a process name -- and it will
use the libproc API so it can match program names longer than 16
characters.

We still have the the issue where running:

    ./dotest.py -v types

we have test failures where the inferior either runs to exited with status 0 or
the inferior stops but not because of breakpoint (for example):

runCmd: process status
output: Process 90060 stopped
* thread #1: tid = 0x2d03, 0x000000010000e2ca, stop reason = EXC_BAD_ACCESS (code=2, address=0x10000e2ca)
  frame #0: 0x000000010000e2ca

There are two cases where the inferior stops for the breakpoint (good), but the expression parser
prints out the wrong information.  The two failures are:

Failure-TestFloatTypesExpr.FloatTypesExprTestCase.test_double_type_with_dsym.log
Failure-TestFloatTypesExpr.FloatTypesExprTestCase.test_double_type_with_dwarf.log

I'll file a radar on the two expression parser misbehave, while continue investigating why the
inferior stops for the wrong reason or does not stop at all.

For now, you'll need to do:

    ./dotest.py -v -w types
