RFR (M): 7177003 C1: LogCompilation support

[Vladimir Ivanov]

Thank you, Vladimir and Chris.

Here are updated changes [1]:
	- merged with the latest changes in hotspot-comp
	- removed intx->int conversion as you suggested
	- removed "receiver is statically known" message from PrintInlining
output, but left in it the log

Best regards,
Vladimir Ivanov
