Julian Lettner	a0884da62a	[NFC][Sanitizer] Pull up GetStackTrace into sanitizer_common ... We already independently declare GetStackTrace in all (except TSan) sanitizer runtime headers. Lets move it to sanitizer_stacktrace.h to have one canonical way to fill in a BufferedStackFrame. Also enables us to use it in sanitizer_common itself. This patch defines GetStackTrace for TSan and moves the function from ubsan_diag.cc to ubsan_diag_standalone.cc to avoid duplicate symbols for the UBSan-ASan runtime. Other than that this patch just moves the code out of headers and into the correct namespace.

Julian Lettner	46e1b16e36	[NFC][Sanitizer] Hard-code fast/slow unwinder at call site ... Also assert that the caller always gets what it requested. This purely mechanical change simplifies future refactorings and eventual removal of BufferedStackTrace::Unwind.

Nico Weber	e3b6d11038	hwasan: Rename source files from cc to cpp ... As discussed elsewhere: LLVM uses cpp as its C++ source extension; the sanitizers should too. This updates files in hwasan. Patch generated by for f in lib/hwasan/*.cc ; do svn mv $f ${f%.cc}.cpp; done followed by for f in lib/hwasan/*.cpp ; do sed -i '' -e '1s/\.cc -/.cpp /' $f; done CMakeLists.txt updated manually.
