Message:

IRQ pseudocode improvements

• rename CMD_BTEST to CMD_AND (less cryptic)
• implement CMD_LOAD to load a constant value into a scratch register
• implement simple pseudocode static checker
• slightly alter the semantics of several pseudocode commands (scratch[0] is a usable field, although not propagated to the IPC notification)
