[svn-r8507] Purpose:
Code optimization
Description:
Eliminate many redundant lookups to check for no-op type conversion by
remembering that a type conversion path is the no-op path.
Also, don't allow non-no-op conversions which happen to be no-ops on a
particular machine (such as int<->long conversions on machines where int and
long are the same size and format, etc.) to replace the default no-op
conversion.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.9 (sleipnir) w/parallel
