Instead of having those `__gshared` constant hiddent in the middle of a very long function, move them to a struct and add documentation.

Adds support for the de-facto standard `SOURCE_DATE_EPOCH` variable, for lexer tokens `__DATE__`, `__TIME__`, `__TIMESTAMP__`.

Moving things to target was a terrible idea. I changed that now, the PR should be much simpler. |

Awesome to see this PR! I tried to build dmd 2.09 with this PR but it doesn't seem compatible. I'll check if it's do-able to build master on Arch. |

Works perfectly for me. Checked on Linux, amd64, with dmd v2.092.0. Thanks! |

I missed this PR, thanks a lot @Geod24! On less thing to worry about when building D code on NixOS ;) |

@Geod24 yes I am interested, and the implementation is wrong. Thanks for crossing me out. :-) $ cat test.c
#include <stdio.h>
void main() { printf(__DATE__ " " __TIME__ "\n"); }
$ SOURCE_DATE_EPOCH=1 gcc test.c -o test-c
$ ./test-c
Jan 1 1970 00:00:01$ cat test.d
import core.stdc.stdio;
void main() { printf(__DATE__ ~ " " ~ __TIME__ ~ "\n"); }
$ SOURCE_DATE_EPOCH=1 dmd test.d -oftest-d
$ ./test-d
