RFR 13 (S): 8196347: LogCompilation: generate log file on the fly for input to junits

[Eric Caspole]

Hi everybody,
Could I have reviews on this change to add setup methods to produce the 
test +LogCompilation files on the fly, so we can test the output of the 
JDK in the repo by adding it into the PATH etc, instead of reading 
static files. Also, this changeset removes several large static input 
files that did not have any special significance. Tested and builds with 
JDK 8 and 13. Nothing prevents adding back useful static log test files 
later, because it is hard to reproduce some constructs on the fly.

Thanks,
Eric
