Bitwise operator priority

[mruz]

php

$t = 1 & 1 << 7;
var_dump($t);

int(0)

zephir

int t;
int u = 1;
int v = 1;
let t = u & v << 7;
var_dump(t);

u = 1;
v = 1;
t = ((u & v) << 7);
ZEPHIR_INIT_VAR(&_10);
ZEPHIR_INIT_NVAR(&_10);
ZVAL_LONG(&_10, t);
zephir_var_dump(&_10);

int(128)

look at this:

php -r "var_dump((1 & 1) << 7);"
int(128)
php -r "var_dump(1 & 1 << 7);"
int(0)

so we shouldn't add parenthes t = ((u & v) << 7); here.

@dreamsxin Could you take a look by any chance?

@sergeyklay $t = 1 & 1 << 7; ===> $t = 1 & (1 << 7);
It needs to be adjusted according to the priority of the operator.
