we don't want this to be converted to:

Rework construction of CXXForRangeStmt not to recycle the same DeclRefExpr in multiple subexpressions.  This breaks the tree structure
of the AST and completely breaks the CFG invariants.

and the breakpoint specification for the benchmark purpose.  This is used by TestSteppingSpeed.py
to benchmark the lldb stepping speed.  Without '-e' and 'x' specified, the test defaults to
run the built lldb against itself and stopped on Driver::MainLoop, then stepping for 50 times.

Allow targets to expand COPY and other standard pseudo-instructions
before they are expanded with copyPhysReg().

This allows the target to examine the COPY instruction for extra
operands indicating it can be widened to a preferable super-register
copy.  See the ARM -widen-vmovs option.

where we can't expand (i.e., multi-level substitution), be sure to
substitute the pack with its level-reduced pack. Fixes PR10230.

The difference between isPseudo and isCodeGenOnly is a bit murky, but
isCodeGenOnly should eventually go away.  It is used for instructions
that are clones of real instructions with slightly different properties.

The standard pseudo-instructions never mirror real instructions, so they
are definitely in the isPseudo category.

Apple only supports libc++ on OS X 10.7 and later but for the open-source

compiled on mips32r1 processors because it uses synci and rdhwr instructions
which are supported only on mips32r2, so I replaced this function with the
call to function cacheflush which works for both mips32r1 and mips32r2.

The table is indexed by opcode, so simply removing pseudo-instructions
creates a wrong mapping from opcode to table entry.

Add a test case for xorps which has a very high opcode that exposes this
problem.

 - Remodel Expr::EvaluateAsInt to behave like the other EvaluateAs* functions,
   and add Expr::EvaluateKnownConstInt to capture the current fold-or-assert
   behaviour.
 - Factor out evaluation of bitfield bit widths.
 - Fix a few places which would evaluate an expression twice: once to determine
   whether it is a constant expression, then again to get the value.

Now that we support move generation, mention this in the language extension and C++ status pages. Also update the C++ status for default functions, which are complete now that we can generate move functions, and destructor exception specifications, which I did a while ago.
