so that they can still be freed after the reference has been changed
(e.g. in case of array indexing or record field accesses) (mantis #33628)

tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
new methods are called get_saved_registers_XXX, where XXX is the register
type ("int", "address", "fpu" or "mm")

register size for OP_SHR/OP_SHL/OP_SAR/OP_ROL/OP_ROR in tcgx86.a_op_reg_reg().
This is required for the in_[shr/shl/sar/rol/ror]_assign_x_y inline nodes.

be used (TBD in a future commit) for optimizing x:=-x and x:=not x on CPUs
that support performing these operations directly in memory (such as x86)

o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now

it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler

necessary

+ new method make_direct_ref() which is used to convert an indirect reference into a direct one (uses the boolean field in_make_direct_ref to avoid recursive calls)
* make_simple_ref: call make_direct_ref() before anything else
* a_loadaddr_ref_ref: call make_direct_ref() (the loading could probably be folded into the loadaddr method, but for now that is sufficent)
