[testsuite] Tweak gcc.dg/ipa/inlinehint-4.c

[Eric Botcazou]

This adds --param inline-unit-growth=20 to the set of options passed to the 
testcase, which is the default setting but makes it possible for the test to 
pass on targets which changes the default, like Visium.

Tested on visium-elf & x86_64-suse-linux, applied on the mainline as obvious.

        * gcc.dg/ipa/inlinehint-4.c: Also pass --param inline-unit-growth=20.
