[ASan] Delete asan/dynamic dir and temporarily move the interposers declarations to asan_intercepted_functions.h
Now that we have only one dependency on asan_intercepted_functions.h, we can unite that code with the interceptors declarations in asan_interceptors.cc and get rid of asan_intercepted_functions.h git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@175631 91177308-0d34-0410-b5e6-96231b3b80d8
