Add option for aligning asterisk and variable name

[alan-gu]

I'm using C++ but I think this could be applied to some other languages.

I have

struct { 
int a;
bool *b;
}

clang format will make it

struct {
int   a;
bool *b;
}

but I want it to be

struct {
int  a;
bool *b;
}

the difference is aligning a to asterisk or to b.
