05b6364eef 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!

6f45959365 Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register 
allocated, thus live across the save/reload.  This fixes

a947d699dd 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.

b231c3d11c 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.

6039769dc1 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.

aa140d6fef For PR804: 
Change the file size field of StatusInfo to be uint64_t instead of size_t
so that we know it is always 64 bits. This prevents some overflow on
systems where size_t is 32 bits when it ought to be 64.

3c338b3803 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.

854aa3ca41 For PR780: 
1. Add #includes to LinkAllVMCore.h to get Mangler.o and InlineAsm.o
2. Make Mangler.h and InlineAsm.h use the macros to ensure linkage
3. Make each of the tools with --load options include LinkAllVMCore.h
