> At the moment `CompileCommand` and `CompileOnly` use different syntax for matching methods. 
> 
> ### Old CompileOnly format
> - matching a **method name** with **class name** and **package name**:
> `-XX:CompileOnly=package/path/Class.method`
> `-XX:CompileOnly=package/path/Class::method`
> `-XX:CompileOnly=package.path.Class::method`
> BUT NOT `-XX:CompileOnly=package.path.Class.method`
> 
> - just matching a **single method name**:
> `-XX:CompileOnly=.hashCode`
> `-XX:CompileOnly=::hashCode`
> BUT NOT `-XX:CompileOnly=hashCode`
> 
> - Matching **all method names** in a **class name** with **package name**
> `-XX:CompileOnly=java/lang/String`
> BUT NOT `-XX:CompileOnly=java/lang/String.`
> BUT NOT `-XX:CompileOnly=java.lang.String`
> BUT NOT `-XX:CompileOnly=java.lang.String::` (This is actually a bug) 
> BUT NOT `-XX:CompileOnly=String`
> BUT NOT `-XX:CompileOnly=String.`
> BUT NOT `-XX:CompileOnly=String::`
> 
> - Matching **all method names** in a **class name** with **NO package name**
> `-XX:CompileOnly=String`
> BUT NOT `-XX:CompileOnly=String.`
> BUT NOT `-XX:CompileOnly=String::`
> 
> - There is a bug when `CompileOnly` ends with `::` where the `CompileOnly` is just ignored
> e.g. `-XX:CompileOnly=String::` compiles as many methods as when omitting the `-XX:CompileOnly=` command
> 
> ### CompileCommand=compileonly format
> `CompileCommand` allows two different forms for paths: 
> - `package/path/Class.method`
> - `package.path.Class::method`
> 
> In contrary to `CompileOnly` `CompileCommand` supports wildcard matching using `*`. `*` can appear at the beginning and/or end of a `package.path.Class` and `method` name. 
> 
>  Valid forms: 
> `-XX:CompileCommand=compileonly,*.lang.*::*shCo*`
> `-XX:CompileCommand=compileonly,*/lang/*.*shCo*` 
> `-XX:CompileCommand=compileonly,java.lang.String::*`
> `-XX:CompileCommand=compileonly,*::hashCode`
> `-XX:CompileCommand=compileonly,*ng.String::hashC*`
> `-XX:CompileCommand=compileonly,*String::hash*`
> 
>  Invalid forms (Error: Embedded * not allowed):
>  `-XX:CompileCommand=compileonly,java.*.String::has*Code`
> 
> ### Use CompileCommand syntax for CompileOnly
> At the moment, in some cases it is not possible to just take pattern used with `CompileOnly` and plug it into compile command file. Syntax used by CompileOnly is also not very intuitive. 
> 
> `CompileOnly` is convenient because it's shorter to write and takes lists of patterns, whereas `CompileCommand` only takes one pattern per command. 
> 
> With this PR `CompileOnly` becomes an alias for `CompileCommand=compileonly` with possibility to take lists as ...
