Print the full structure of all rtx insns beginning at $.

Uses variable debug_rtx_count to control number of insns printed:

debug_rtx_count > 0: print from $ on.
|
|
debug_rtx_count < 0: print a window around $.
|
|
|
|
There is also debug_rtx_find (rtx, uid) that will scan a list for UID and print
|
|
it using debug_rtx_list. Usage example: set $foo=debug_rtx_find(first, 42)
