9686ae7f4e Teach bugpoint to kill optimization passes that run over the timeout limit, 
which allows it to debug optimizer infinite loops.  This patch is contributed
by Nick Lewycky, thanks!

e67304fb78 Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register

3d2aa47bd3 Fix for 2006-06-26-MultipleExitsSingleBlock. 
If a single exit block has multiple predecessors within the loop, it will
appear in the exit blocks list more than once.  LCSSA needs to take that into
account so that it doesn't double process that exit block.

4a45abf66e Fix a problem exposed by the local allocator. CALL instructions are not marked 
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

86c75d3113 RewriteExpr, either the new PHI node of induction variable or the 
post-increment value, should be first cast to the appropriated type (to the
type of the common expr). Otherwise, the rewrite of a use based on (common +
iv) may end up with an incorrect type.

32f5553c03 For PR787: 
Provide new llvm::sys::Program facilities for converting the stdout and
stdin to binary mode. There is no standard way to do this and the available
mechanisms are platform specific. Adjust the bytecode reader and writer to
use these methods when their input is stdin or output is stdout. THis avoids
the problem with \n writing CRLF to a bytecode file on windows.

Patch Contributed by Michael Smith.
