12565159bf Don't check variables before they are set.
Be careful about blanks when checking LLVMGCC variable.

5cd496e727 Live local variables are being dropped because the begin or end labels marking
their scope are being deleted.  Workaround is to widen scope to full function.

af53a87052 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.

e077ef6e85 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.

118c094176 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.
