commit 329747ca1c0fc80010ac55f2fa41c22d3c56c1a0
Author: Alexis Hetu <sugoi@google.com>
Date: Fri Apr 13 12:07:22 2018

Added check for temporary register overflow

Currently, when overflowing the number of temporary registers
allowed, SwiftShader will crash somewhere in the generated
code. This cl adds an early check to prevent the crash and
instead output an error message to the user.
