More detail when tracking out_val leaks
Ensure out_op() consumes both lhs and rhs
Ensure out_op() callees correctly update the lhs/rhs

For memory/leak reasons
Correct reference counting in compound assignment
out_cast() stores the new type
Warn-unused-result on impl_* functions - fix impl_load()
Put x86 floating point value loads back in
Put backend commenting back in
Correct type for a global variable out_push_sym()
x86 intval loading (64-bit integers)
Implement out_new_zero()
Make new.c:TODO() fatal
Switch creates its case/default basic-blocks before code-gen
Create default case's basic block
Correct retain handling of the switch value
No extra tab in x86 flag jump logic
Corrected switch jumps - were inverted
