Revert "Replace __FUNCTION__ with __func__, the latter being standard C99/C++11."
...
This reverts commit r201910.
While __func__ may be standard in C++11, it was only recently added to
MSVC in 2013 CTP, and LLVM supports MSVC 2012. __FUNCTION__ may not be
standard, but it's *very* portable.

[asan] Do all calls to __asan_report_* through PLT.
...
This matters when runtime is built as a shared library. Even though calling
code is itself part of the same library, these symbols are public and can
(theoretically) be interposed.
It might be better to declare hidden aliases for asan_report_* and call them
directly, but
(a) they are (noreturn), so performance does not matter, and
(b) it may be potentially less portable.
