RFR: JDK-8198751 Refactor SetupNativeCompilation to take NAME and TYPE

Tue Feb 27 11:15:45 UTC 2018

Currently, SetupNativeCompilation takes as "main" argument either
LIBRARY := $name, PROGRAM := $name or STATIC_LIBRARY := $name.

This confounds two distinct concepts: the name of the generated binary, 
and the type of binary to create. Instead, we should have a NAME 
argument and a TYPE argument.

I also took the liberty of updating the code to more modern standards 
wrt whitespace, and fixed the "Yoda style" if conditions.
