Richard Smith 864711ee9f Reduce recursion limit on this test further to try to make the msys bot green.

Richard Smith f6f003af6a C++11 constexpr: Add note stacks containing backtraces if constant evaluation
fails within a call to a constexpr function. Add -fconstexpr-backtrace-limit
argument to driver and frontend, to control the maximum number of notes so
produced (default 10). Fix APValue printing to be able to pretty-print all
APValue types, and move the testing for this functionality from a unittest to
a -verify test now that it's visible in clang's output.

Richard Smith 9af58d4426 Halve the constexpr recursion depth in this test in an attempt to make the
freebsd bots happy. In the longer term, we should have a mechanism for moving
constexpr recursion off the call stack, to support the default limit of 512
suggested by the standard.

Richard Smith 357362d00b Add checks and diagnostics for many of the cases which C++11 considers to not
be constant expressions.

Richard Smith 9ca5c42582 Update all tests other than Driver/std.cpp to use -std=c++11 rather than
-std=c++0x. Patch by Ahmed Charles!

Douglas Gregor fcafc6e3de Implement the initial part of C++0x [expr.const]p2, which specifies
that the unevaluated subexpressions of &&, ||, and ? : are not
considered when determining whether the expression is a constant
expression. Also, turn the "used in its own initializer" warning into
a runtime-behavior warning, so that it doesn't fire when a variable is
used as part of an unevaluated subexpression of its own initializer.

Fixes PR9999.
