Incorrect Lvalue conversion when using inline assembly

[Thierry Delisle]

Given the following code :

void bts(unsigned long long int * target, unsigned long long int bit ) {
	asm (
            "LOCK btsq %[bit], %[target]\n\t" :
            : [target] "m" (*target), [bit] "r" (bit)
	);
}

The code generator incorrectly generates code missing the * in front of target as follows:

void _X3btsFv_Pyy__1(unsigned long long int *_X6targetPy_1, unsigned long long int _X3bity_1){
    asm ( "LOCK btsq %[bit], %[target]\n\t" :  : [ target ] "m" ( _X6targetPy_1 ), [ bit ] "r" ( _X3bity_1 ) :  );
}

It should generate:

void _X3btsFv_Pyy__1(unsigned long long int *_X6targetPy_1, unsigned long long int _X3bity_1){
    asm ( "LOCK btsq %[bit], %[target]\n\t" :  : [ target ] "m" ( *_X6targetPy_1 ), [ bit ] "r" ( _X3bity_1 ) :  );
}

Modified Lvalue cast handling to ignore top level dereferencing in AsmExpr, also added test case for this fixes #152
