RFR(S): 8138756: Compiler Control: Print directives in hs_err

[Nils Eliasson]

Hi,

Please review this small change. The diff looks big but most of the 
change is just changing how the directive are passed to the compilers. 
Directives are set in the ciEnv and then passed to the compilers. The 
compilers can then choose to add it to any internal compilation object 
for convenience. The hs_err printing routine in vmError.cpp loads the 
directive from the ciEnv.
