[PATCH 2/2] fix expression type for floating point !

[Xi Wang <xi.wang@gmail.com>]

Run test-linearize against this program.

	static int foo(float x) { return !x; }

The output is:

	set.32      %r2 <- 0.000000
	bad_op.32
	ret.32      %r3

The expression type of zero testing should be EXPR_COMPARE, rather than
EXPR_BINOP, which causes bad_op.
