Testsuite: Make it easier to debug environment setting functions

This adds verbose output to dg-set-compiler-env-var and dg-set-target-env-var
so you can actually see what they're setting when you add -v -v.

gcc/testsuite/ChangeLog:

	* lib/gcc-dg.exp (dg-set-compiler-env-var, dg-set-target-env-var): Add
	verbose output.

(cherry picked from commit e410cbff5d5a408b7c64a0c426951afc2a24df93)
