Subject: [mips] The naming convention for private labels is ABI dependant.

Summary:
For N32/N64, private labels begin with '.L' but for O32 they begin with '$'.

MCAsmInfo now has an initializer function which can be used to provide information from the TargetMachine to control the assembly syntax.
