mozjpeg/simd/x86_64/jdcolext-sse2.asm
DRC eb75363004 Update URLs 
- Eliminate unnecessary "www."
- Use HTTPS.
- Update Java, MSYS, tdm-gcc, and NSIS URLs.
- Update URL and title of Agner Fog's assembly language optimization
  manual.
- Remove extraneous information about MASM and Borland Turbo Assembler
  and outdated NASM URLs from the x86 assembly headers, and mention
  Yasm.
