This particular issue isn't clang-specific; it affects MSVC as well, and I
believe clang's -fdelayed-template-parsing attempts to model MSVC's behavior.
See https://godbolt.org/g/xrbpgX (code in https://reviews.llvm.org/P8012).

Log:
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.
