Issue 1437 : Bitmap #decompress:fromByteArray:at: not wellformed

the primitive method #decompress:fromByteArray:at: aren't well-formed, cause the code of this 
method is using by VMMaker to generate source code of the primitive, then it can happen which a 
selector using in the method was never implemented.

Then if the code is fix VMMaker may not be able to generate a clean source code.

the main point of this issue is the selector call: #primitiveFail, he doesn't exist in the Pharo 
environment and seem be change by #primitiveFailed which exist, and then the mistake can't be see 
if we don't try to generate to use VMMaker without using MiscPrimitivesPlugin.

I post a fix in the Inbox.
