Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.

Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

[Sanitizer] Modify CMake build rules for sanitizer_common unit tests: build them with fresh Clang for both 32- and 64-bits (if possible)

This test didn't pass for me locally because of "T0's stack" being converted to "T0'short stack" by c++filt.
Strange enough this doesn't show up on our bots.

FYI, llvm and clang can be built deterministically between stage 2 and stage3, among iterative clean rebuilds, with GNU ar;

access and ambiguity for a derived-to-base conversion. This passes all
is_base_of tests in the test suite.
