For the testing that constants have the correct type, start with the macro 
definitions from c99-instconst-1.c (CHECK_HEX_CONST can be converted to 
what you need by changing 0x and 0X to 0b and 0B) but replace the function 
foo with one checking the binary versions of the hex constants presently 
checked.  (The macros dealing with decimal constants can be removed as 
irrelevant for binary.)
