RFR 8134931: jdk.nashorn.internal.codegen.TypeMap should not use Map

[Michael Haupt]

Hi Sundar,

with any particular TypeMap instance hanging off of a node, and all of its members constant, I think some of the logic throughout the class can be reduced by means of constant folding. For instance, getCallSiteType() doesn't really have to do the appendParameterTypes() sequence every time. The result could be computed once and cached. Likewise for other methods.

Best,

Michael
