Alex Denisov a3f5c4c047 Replace hardcoded comment at 'lit.site.cfg.in'
At the moment almost every lit.site.cfg.in contains two lines comment:

  ## Autogenerated by LLVM/Clang configuration.
  # Do not edit!

The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from
configure_lit_site_cfg with the note and some useful information.

The tests in this directory use a common convention for exercising the
functionality associated with bit sets of different sizes. When certain
macros are defined the tests instantiate classes that force the bit sets
to be of certain sizes.

- B32 forces 32-bit bit sets.
- B64 forces 64-bit bit sets.
- BM forces memory bit sets.
