1) Fix IPF ICC 11.1 issue when /Ox is used related to the use of local variables and parameter across the transition when TEMP RAM is disabled.

Browse Source 
2) Update the logic that computes the offset of the heap and stack from TEMP RAM to Permanent RAM to handle all possible offsets values.
3) Minor cleanups to the PEI_CORE_INSTANCE structure
4) Simplify the logic that manages the TEMP RAM to PERM RAM transition and clean up the related DEBUG() messages.
