Raman Tenneti a72499e475 [libc] Introduce asctime, asctime_r to LLVM libc
[libc] Introduce asctime, asctime_r to LLVM libc

asctime and asctime_r share the same common code. They call asctime_internal
a static inline function.

asctime uses snprintf to return the string representation in a buffer.
It uses the following format (26 characters is the buffer size) as per
7.27.3.1 section in http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2478.pdf.
The buf parameter for asctime_r shall point to a buffer of at least 26 bytes.

snprintf(buf, 26, "%.3s %.3s%3d %.2d:%.2d:%.2d %d\n",...)
