expr.h:
...
nuke the ex_statement and estatement_[st] stuff
add label_expr prototype
expr.c:
ex_statement nukage
correct new_expr's decl
add label_expr to ease label creation
don't crash when printing a null expression (bare return)
qc-parse.y:
estatement_t nukage
statement statements and statement_block are type expr
generate `expressions' for statements
a full parse tree for each function is now generated. there are several
special expression opcodes for statements:
d done \
r return -> unary: expression to return or null
i if binary: evaluated expression, destination label
n ifnot binary: evaluated expression, destination label
c call binary: function def, args (expr list, rev order)
s state binary: frame const, function def
g goto unary: destination label
l label unary: label number
in a top level expression, l (label) defines the label, otherwise it is a
reference.
