Write CodeView information about enregistered optimized variables
Enable variable tracking when outputting CodeView debug information, and make
it so that we issue debug symbols for optimized variables in registers. This
consists of S_LOCAL symbols, which give the name and the type of local
variables, followed by S_DEFRANGE_REGISTER symbols for the register and the
code for which this applies.
