ishell d9e8764f81 [ic] Split LoadIC into LoadGlobalIC and LoadIC. 
The former will handle loads of predeclared global variables (vars and
functions), lets, consts and undeclared variables. The latter will handle
named loads from explicit receiver. In addition, named loads does not
depend of the TypeofMode.

TypeofMode related cleanup will be done in the follow-up CL.
