[libc] apply new lint rules
This patch applies the lint rules described in the previous patch. There
was also a significant amount of effort put into manually fixing things,
since all of the templated functions, or structs defined in /spec, were
not updated and had to be handled manually.

[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",...)

Changes to mktime to handle invalid dates, overflow and underflow andcalculating the correct date and thenumber of seconds even if invalid datesare passed as arguments.
Added tests for invalid dates like the following
Date 1970-01-01 00:00:-1 is treated as 1969-12-31 23:59:59 and seconds
are returned for the modified date.
Tested the code by doing ninja check-libc (and cmake).

[libc][NFC] add "LlvmLibc" as a prefix to all test names
Summary:
Having a consistent prefix makes selecting all of the llvm libc tests
easier on any platform that is also using the gtest framework.

Summary:

This also modifies the TEST and TEST_F macros to enforce this change
moving forward.

Initial commit of mktime.
This introduces mktime to LLVM libc, based on C99/C2X/Single Unix Spec.
Co-authored-by: Jeff Bailey <[email protected]>
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
