cmath: Support clang's -fdelayed-template-parsing
r283051 added some functions to cmath (in namespace std) that have the same name as functions in math.h (in the global namespace). Clang's limited support for `-fdelayed-template-parsing` chokes on this. Rename the ones in `cmath` and their uses in `complex` and the test. rdar://problem/32848355 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@307357 91177308-0d34-0410-b5e6-96231b3b80d8
