Arrange to print constants that match "n" and "i" constraints
...
in inline asm as signed (what gcc does). Add partial support
for x86-specific "e" and "Z" constraints, with appropriate
signedness for printing.

Make a transformation added in 63266 a bit less aggressive.
...
It was transforming (x&y)==y to (x&y)!=0 in the case where
y is variable and known to have at most one bit set (e.g. z&1).
This is not correct; the expressions are not equivalent when y==0.
I believe this patch salvages what can be salvaged, including
all the cases in bt.ll. Dan, please review.

After visiting a BB if it find a successor which has a single predecessor it visits the successor next without clearing the availability information.
