Issues building graal-jvmci-8 with Cygwin

[Svata Dedic]

Hi,

the UNIX launcher script was not tested at all under cygwin. I believe 
neither NetBeans (platform for IGV) tested the shell launcher on 
windows. It was expected that windows users will run the .exe launchers 
instead.

Will investigate / fix, but it could be rather hard to prepare script 
which runs on MacOS, Linxues AND cygwin :)

Unless you provide --jdkhome switch on commandline to the .exe launcher, 
it will look in the Windows Registry to find the JDK location in this order:
* JDK 9+ (Software\JavaSoft\JDK)
* JRE 9+ (Software\JavaSoft\JRE)
* older JDK (Software\JavaSoft\Java Development Kit)
* older JRE (Software\JavaSoft\Java Runtime Environment)
in each case CurrentVersion is used, so whatever jdk is the newest, or 
configured for the system AND exists.

Please file a bug on not being able to run on JDK10+. The latest NB 
platform should already address this.

It also seems I have to add some hook into platform sources, because (I 
think) standard NB-application launchers do not even suppose they could 
be bundled with JDK (and should use that one, if it is the case). 
Another bug.

In the meantime, please use
	--jdkhome path/to/jdk/installation
switch on IGV's commandline
