JDK-8177481 - Prepare Runtime code for -Wconversion
Description
Runtime code in the oops directory stores 'int' values into 'u2' containers for ConstantPool and ConstMethod.  Changing return types to u2 and using u2 as variables, avoids -Wconversion warnings in these source files.  There's some fan out.  To avoid infinite fan out, added some check_cast<u2> casts for types known to be u2 as specified in the JVMS.
