Initial commit of mktime. This introduces mktime to LLVM libc, based on C99/C2X/Single Unix Spec. Co-authored-by: Jeff Bailey <jeffbailey@google.com> 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 Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D91551

[libc] Add initial assert definition Summary: This patch adds a temporary `__assert_fail` and `assert` definition to make it available to internal llvm libc code. `__assert_fail` writes to fd 2 directly instead of `stderr`, using SYS_write. I have not put it in its own linux directory because this is temporary and it should be using stdio's api in the future. It does not currently print out the line number (although we could do that by stringifying `__LINE__` if reviewers wish).

[libc] Add implementations long double fabsl and truncl functions. Current implementations of single precision and double precision floating point operations operate on bits of the integer type of same size. The code made use of magic masks which were listed as literal integer values. This is not possible in the case of long double type as the mantissa of quad-precision long double type used on non-x86 architectures is wider that the widest integer type for which we can list literal values. So, in this patch, to avoid using magic masks specified with literal values, we use packed bit-field struct types and let the compiler generate the masks. This new scheme allows us to implement long double flavors of the various floating point operations. To keep the size of the patch small, only the implementations of fabs and trunc have been switched to the new scheme. In following patches, all exisiting implementations will be switched to the new scheme. Reviewers: asteinhauser Differential Revision: https://reviews.llvm.org/D82036

[libc] Add implementations long double fabsl and truncl functions. Current implementations of single precision and double precision floating point operations operate on bits of the integer type of same size. The code made use of magic masks which were listed as literal integer values. This is not possible in the case of long double type as the mantissa of quad-precision long double type used on non-x86 architectures is wider that the widest integer type for which we can list literal values. So, in this patch, to avoid using magic masks specified with literal values, we use packed bit-field struct types and let the compiler generate the masks. This new scheme allows us to implement long double flavors of the various floating point operations. To keep the size of the patch small, only the implementations of fabs and trunc have been switched to the new scheme. In following patches, all exisiting implementations will be switched to the new scheme. Reviewers: asteinhauser Differential Revision: https://reviews.llvm.org/D82036
