0b17b45a96 Do not CopyFromReg physregs for live-in values. Instead, create a vreg for 
each live in, and copy the regs from the vregs.  As the very first thing we
do in the function, insert copies from the pregs to the vregs.  This fixes
problems where the token chain of CopyFromReg was not enough to allow reordering
of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers
eax on intel).

61d9d81770 calling a function with the wrong CC is undefined, turn it into an unreachable

39ec7f049d Make sure that decompression checks for the case that bzip2 returns 
BZ_OK (meaning more data is expected) but there is no more input data. In
this case, the input file is probably truncated. Generate an exception that
indicates this case when its detected.

99fa5bc1fa Necessary changes to codegen cttz efficiently on PowerPC 
1. Teach LegalizeDAG how to better legalize CTTZ if the target doesn't have
   CTPOP, but does have CTLZ
2. Teach PPC32 how to do sub x, const -> add x, -const for valid consts
3. Teach PPC32 how to do and (xor a, -1) b -> andc b, a
4. Teach PPC32 that ISD::CTLZ -> PPC::CNTLZW

06bbeb646f Fix the last remaining bug preventing us from switching the X86 BE over 
from the simple isel to the pattern isel.  This forces inserted libcalls
to serialize against other function calls, which was breaking
UnitTests/2005-05-12-Int64ToFP.  Hopefully this will fix issues on other
targets as well.
