tcg: Reindent parts of liveness_pass_1
There are two blocks of the form if (foo) { stuff1; goto bar; } else { baz: stuff2; } which have unnecessary and confusing indentation. Remove the else and unindent stuff2. Reviewed-by: Emilio G. Cota <cota@braap.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
