systemtap/916
Implement all basic scalar operators, including modify-assignment.
* parse.cxx (lexer): Allow multi-character lookahead in order to
scan 1/2/3-character operators.
(parse_boolean_or/and/xor/shift): New routines.
* translate.cxx (visit_assignment, visit_binary_expression,
visit_*_crement): Generally rewrote.
(visit_*): Added more parentheses in output.
(emit_module_init): Initialize globals.
* staptree.h, elaborate.cxx, elaborate.h: Remove exponentiation.
* main.cxx (main): Add an end-of-line to output file.
* testsuite/*: Several new tests.
