Splits fuchsia-default-arguments check into two checks. fuchsia-default-arguments-calls warns if a function or method is called with default arguments. fuchsia-default-arguments-declarations warns if a function or method is declared with default parameters. Committed on behalf of @diegoast (Diego Astiazarán). Resolves b38051. Differential Revision: https://reviews.llvm.org/D62437 llvm-svn: 363712
