tinycc x86 platform __fastcall bug.

Example code:

///////////////////////////////////////////////

#include <stdio.h>

void __fastcall go(double d)

{

        printf("go fastcall: %f\n", d);

}

void __cdecl go2(double d)

{

        printf("go cdecl: %f\n", d);

}

void __fastcall gof(float d)

{

        printf("go fastcall float: %f\n", d);

}

void __fastcall golong(__int64 n)

{

        printf("go fastcall int64: 0x%016I64X\n", n);

}

int main(int argc, char * argv[])

{

        double pi = 3.14;

        go(pi);

        go2(pi);

        gof((float)pi);

        golong(0x1234567812345678UL);

        return 0;

}

tcc run the above code, output:

go fastcall: 0.000000

go cdecl: 3.140000

go fastcall float: 3.140000

go fastcall int64: 0x003AFACC12345678
