get_type and extract_type prototypes and add extern for type_names
emit.c:
use extract_type instead of get_type
expr.c:
get_type now returns the type pointer rather than the qc type enum.
extract_type uses get_type to return the qc type enum.
make type_names global
use get_type instead of ex_expr/ex_def to cover more cases
clean up function call/return processing as a result of get_type
pr_opcode.c:
use opcode_priority_type_table_ab when var_c is null and a minor
cleanup in PR_Opcode_Find
*/CRITICAL/* implication: DO NOT /EVER/ RELY ON EVALUATION ORDER. This
isn't /really/ that bad: evaluation order will be consistent for similar
expressions, but for (eg) foo() + bar()*2, bar will be called first.
use reference counting for temp defs and call PR_FreeTempDefs at the end
of emit_sub_expr as well as emit_expr.
fix a (relatively harmless) bug in type processesing of foo.bar =
