Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions.
I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.
Test updates are made as a separate patch: D108453

[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default (2)
This patch updates test files after D105169.
Autogenerated test codes are changed by `utils/update_cc_test_checks.py,` and non-autogenerated test codes are changed as follows:
(1) I wrote a python script that (partially) updates the tests using regex: {F18594904} The script is not perfect, but I believe it gives hints about which patterns are updated to have `noundef` attached.
(2) The remaining tests are updated manually.

We still support the old mangling if we're trying to be ABI-compatible with
Clang 6.0, though.

As described by Richard in https://groups.google.com/a/isocpp.org/d/msg/std-discussion/S1kmj0wF5-g/fb6agEYoL2IJ
we should allow:
template<typename S>
struct A {
template<typename T> static auto default_lambda() {
return [](const T&) { return 42; };
}
template<class U = decltype(default_lambda<S>())>
U func(U u = default_lambda<S>()) { return u; }
};
int run2 = A<double>{}.func()(3.14);
int run3 = A<char>{}.func()('a');
This patch allows the code using the same trickery that was used to allow the code in non-member functions at namespace scope.
Please see http://llvm-reviews.chandlerc.com/D1844 for richard's approval.
