Suppress warnings from v3_kernel when inlining is turned on
v3_kernel may produce unwanted and confusing warnings for code that has been inlined with the new inliner (cerl_inline). Consider this code: -compile(inline). compute1(X) -> add(X, 0). compute2(X, Y) -> add(X, Y). add(1, 0) -> 1; add(1, Y) -> %% "this clause cannot match..." 1 + Y; add(X, Y) -> X + Y. v3_kernel warns because add/2 has been inlined into compute1/1 and only the first clause in add/2 will match. But the other clauses are needed when add/2 is inlined into compute2/2, so the user cannot do anything to eliminate the warning (short of manually inlining add/2, defeating the purpose of the 'inline' option). The warning would be reasonable if compute2/2 didn't exist, but it would be too complicated for the compiler to figure whether a warning make sense or not. Therefore, suppress all warnings generated by v3_kernel if cerl_inline has been run. ERL-301
