e993f46de9 Modify the lines of code counting mechanism to use the new "countloc.sh" 
utility. This avoids some problems with long line lengths and counting the
wrong things.

65e731d99a Added a tool to more accurately count the lines of code. The previous 
utility, getsrcs.sh suffered from two problems: (1) it generated command
lines too long for some platforms and (2) it searched the projects diretory
which now contains the llvm-test module (in nightly tester) but we don't
want to include the test code in our LOC calculation. This script should
be maintained as LLVM adds new top level directories that contain source
code.

eedba5e824 * CSS was created to reduce re-specifying design styles: specify table cell 
color once at the top, and do not repeat it 82 times
* Replace bright blue table border with gray, which is easier on the eyes and
  matches the gray LLVM documentation color scheme

* Adjust Makefile accordingly

e2c6f51e2b Don't just assume that either uint64_t or u_int64_t is available. Instead, 
give preference to uint64_t if it exists. If not, check for u_int64_t. If
that doesn't exist either, then error out.
