compiler: Avoid unnecessary getEnvironment usagewip/drop-getEnvironment
In general getEnvironment can be quite expensive since it must decode
the entire environment (which may be large) into a String.
On non-Windows platforms
Previously `GHC.SysTools.Process.getGccEnv`, which exists only to work
around a toolchain bug on Windows (#1110), called `getEnvironment` on
POSIX only to then pass the environment unmodified, incurring
unnecessary cost. Don't do this.
