Initial commit of mktime.

2020-12-01T05:07:16+00:00

This introduces mktime to LLVM libc, based on C99/C2X/Single Unix Spec.

Co-authored-by: Jeff Bailey 

This change doesn't handle TIMEZONE,  tm_isdst and leap seconds.  It returns -1 for invalid dates. I have verified the return results for all the possible dates with glibc's mktime.

TODO:
+ Handle leap seconds.
+ Handle out of range time and date values that don't overflow or underflow.
+ Implement the following suggestion Siva - As we start accumulating the seconds, we should be able to check if the next amount of seconds to be added can lead to an overflow. If it does, return the overflow value.  If not keep accumulating. The benefit is that, we don't have to validate every input, and also do not need the special cases for sizeof(time_t) == 4.
+ Handle timezone and update of tm_isdst

[libc] Add very basic stdio FILE and fwrite

2020-04-14T08:02:27+00:00

Summary:
This patch adds a very basic `FILE` type and basic `fwrite`.

It also removes `snprintf` from `StdIO`'s function spec because `VarArgType` was causing the generation to fail.

Only targets setup by the special LLVM libc rules now have fully

Python.
