  Message : Support multiple nested ternary operators per statement TRAC #18382 ANGLEBUG=203,208 Signed-off-by: Daniel Koch Author: Nicolas Capens - by incrementing the temporary index, adding 1 for every nesting level, and rewinding it after each traverse. Also fixed multiple ternary operator unfolding for loops. git-svn-id: https://angleproject.googlecode.com/svn/trunk@784 736b8ea6-26fd-11df-bfd4-992fa37f6226
