Added the ability to specify a breakpoint using the GDB '*ADDRESS' format:

(lldb) b *0x1234

You can still of course just specify an address:

(lldb) b 0x1234

Also now we accept the '&' before function names to indicate to not to skip the function prologue like GDB supports. To see how this works:

(lldb) settings set interpreter.expand-regex-aliases 1
(lldb) b &main
breakpoint set --name 'main' --skip-prologue=0
Breakpoint 1: where = a.out`main at main.c:20, address = 0x0000000100000b60
(lldb) b main
breakpoint set --name 'main'
Breakpoint 2: where = a.out`main + 54 at main.c:21, address = 0x0000000100000b96
