Arthur Eubanks f59311e31d Mark lambda in use-after-scope-capture.cpp as noinline
Summary:
As explained in https://bugs.llvm.org/show_bug.cgi?id=46208,
symbolization on Windows after inlining and around
lambdas/std::functions doesn't work very well. Under the new pass
manager, there is inlining at -O1.
use-after-scope-capture.cpp checks that the symbolization points to the
line containing "return x;", but the combination of
Windows/inlining/lambdas makes the symbolization point to the line
"f = [&x]() {".

Mark the lambda as noinline since this test is not a test for
symbolization.
