David Turner b28908860d Optimize FT_MulFix for x86_64 GCC builds.
This patch provides an optimized `FT_MulFix' implementation for
x86_64 machines when FreeType is built with GCC, or compatible
compilers like Clang.

Example:
  bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf

Before:

  Load                       4.863 us/op
  Load_Advances (Normal)     4.816 us/op
  Load_Advances (Fast)       0.028 us/op
  Render                     2.753 us/op
  Get_Glyph                  0.463 us/op
  Get_CBox                   0.077 us/op
  Get_Char_Index             0.023 us/op
  Iterate CMap              13.898 us/op
  New_Face                  12.368 us/op
  Embolden                   0.028 us/op
  Get_BBox                   0.302 us/op

After:

  Load                       4.617 us/op
  Load_Advances (Normal)     4.645 us/op
  Load_Advances (Fast)       0.027 us/op
  Render                     2.789 us/op
  Get_Glyph                  0.460 us/op
  Get_CBox                   0.077 us/op
  Get_Char_Index             0.024 us/op
  Iterate CMap              13.403 us/op
  New_Face                  12.278 us/op
  Embolden                   0.028 us/op
  Get_BBox                   0.301 us/op
