[diagtool] Change default tree behavior to print only flags This patch changes the default behavior of `diagtool tree` to only display warning flags and not the internal warnings flags. The latter is an implementation detail of the compiler and usually not what the users wants. Furthermore, flags that are enabled by default are now also printed in green. Originally, this was only the case for the diagnostic names. Differential revision: https://reviews.llvm.org/D37390 llvm-svn: 312546

Add specific warning flags for GNU ext in Sema. This patch adds the following, more specific warning flags: gnu-anonymous-struct gnu-compound-literal-initializer gnu-empty-struct gnu-flexible-array-initializer gnu-flexible-array-union-member gnu-folding-constant redeclared-class-member gnu-redeclared-enum gnu-union-cast gnu-variable-sized-type-not-at-end Patch by Peter Lewis. llvm-svn: 190972
