Register pass has the its last user, otherwise sometimes no one will claim
LastUse.

  patterns.

patch by Lauro

llvm-svn: 32577

If a spillslot value is available in a register, and there is a noop copy that
targets that register, the spiller correctly decide not to invalidate the
spillslot register.

However, even though the noop copy does not clobbers the value. It does start a
new intersecting live range. That means the spillslot register is available for
use but should not be reused for a two-address instruction modref operand which
would clobber the new live range.

When we remove the noop copy, update the available information by clearing the
canClobber bit.

Use PDL as the prefix for these enums.
Define and use PassDebugging_New in new PassManager.

used to determine whether a ZExt or SExt cast is performed. Instead, pass
an "isSigned" bool to the function and determine its value from the opcode
of the cast involved.
Also, clean up some cruft from previous patches.

cast instructions. A few are bug fixes.

make sure to also check that it is a zext from bool, not any other cast
operation type.

The cast patch introduced the possibility that the wrong cast opcode
could be used and that this transform could trigger on different kinds
of cast operations. This patch rectifies that.

so the decision of which opcode to use is pushed upward to the caller.
Adjust the callers to pass the expected opcode.

continue to use old pass manager at the moment. To use new manager
remove #define USE_OLD_PASSMANAGER 1 from Pass.h
