a193c9c977 encode BLR predicate info for the JIT 
llvm-svn: 31450

a7687f805c Go through all kinds of trouble to mark 'blr' as having a predicate operand 
that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.

8dac4564af Parse PredicateOperand's. When an instruction takes one, have the generated 
isel fill in the instruction operands with the 'execute always' value
automatically.

f7ad33f01b First steps to getting PredicateOperand's to work. This handles instruction 
and pat pattern definitions.  Codegen is not right for them yet.

A little script to return 1 if it encounters any of the cast instructions
on the stdin.

4328919c08 Fixed some spiller bugs exposed by the recent two-address code changes. Now 
there may be other def(s) apart from the use&def two-address operand. We need
to check if the register reuse for a use&def operand may conflicts with another
def. Provide a mean to recover from the conflict if it is detected when the
defs are processed later.

8a81e9e264 Split the External and Intrinsic handling into seperate functions. This 
improves readability of the call handling code significantly, as well as
makes it clear which parts are hacky (externals) and which parts are good
(call handling).

No functionality change.
