Simple main C program decompiled wrong

Are you mostly interested in Delphi? Below is a simple C program, for which decompiler confuses arguments in a weird way.

commit 1da7146b9a4d4c777eff73a975337d84f7ab0e17

```c
$ cat test.cc
#include

volatile double val = 6.0;

int main(int argc, char* argv[])
{
int result = 0;
if (argc > 1)
result = (int)val + argc;
else
result = (int)val - argc;

printf("result = %d\n", result);

return result;
}
```

```
$ gcc -m32 -O0 test.cc -o test
```

```
$ ./retdec-decompiler.sh ./test
##### Checking if file is a Mach-O Universal static library...
...
##### Done!
```

```c
$ cat test.c

int32_t v2 = argv > (char **)1 ? v1 : -v1;
int32_t result = (int32_t)g1 + v2;
printf("result = %d\n", result);
return result;
}

```

The resulting code is seriously broken: instead of checking `argc`, it *somehow* ends up checking the value of `argv`. Obviously, the result is completely wrong:

```
$ gcc -O0 -m32 test.c -o test.check
```

```
$ ./test 1
result = 8

$ ./test.check 1
result = -7295126
```

Reproduce the report using commit 1da7146b9a4d4c777eff73a975337d84f7ab0e17, test.cc, gcc -m32 -O0, and retdec-decompiler.sh. Compare the generated test.c with the original and run both binaries using an argument such as ./test 1. Done means the decompiled program checks argc and produces the same result as the original.
