so it also works for 32 bit targets and a high level code generator
(where aint is still 32 bit, but 64 bit operations are not decomposed)

(cherry picked from commit 07bd4ba517)
With local change to fix compilation for x86_64 CPU
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

* Change MIPS jump tables in PIC mode to use gp-relative constants, making them ABI-compliant and not requiring dynamic relocations.
git-svn-id: trunk@26886 -
* Moved jump tables into data segment. For disassembly-based stack unwinding to work properly, MIPS ABI expects text segment to contain instructions only.

o changed type of opsize field of tcgcasenode from tcgsize into tdef,
and fixed compilation of other code generator units after this change
