ccb33335a3 Allow copy coalescing in more cases: if sum of node degrees is more than 
than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.

6f0ad9998b Moving these files from Code/PreSelection to here. 
Original logs for PreSelection.cpp:

  revision 1.2
  date: 2002/09/17 23:50:32;  author: lattner;  state: Exp;  lines: +1 -3
  Don't put default parameter values into .cpp files, it breaks 3.x compilers

  revision 1.1
  date: 2002/09/16 15:31:13;  author: vadve;  state: Exp;
  New preselection pass that specializes LLVM code for a target machine,
  while remaining in legal portable LLVM form and preserving type
  information and type safety.

a506baf8bd Reenable these options because they break testing on sparc without them. 
Conditionalizing them on DISABLE_LLC means they aren't enabled under linux.

  is not in the place specified by the platform makefile.

220855bab6 It turns out that the cannonical name for the llvm-gcc compiler is, well 
llvm-gcc, not gcc.

c86c7ecdb5 Make sure that we abort if an error happens as early as neccesary. Before 
it was possible for the passmanager to continue running passes after the
verifier even if the module was not well formed.

c3d678fff5 gcc3.1.1 seems much more selective about what it loads from archives, and 
does not link in many passes that are loaded by gcc2.95.3.  So use object
files instead of archives in many more cases.
