sysv_abi_cdecl calling conventions on x86-64 to force using the SYSV/
Microsoft ABI on platforms that don't use it by default (mainly to ease
porting pure assembler routines)
git-svn-id: trunk@35425 -
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

x86-64 platforms (except for win64, which uses another ABI and which
already complied to it) + test
* fixed returning records containing 1 single or double field on darwin/i386,
these have to be returned via ST0 instead of as a regular record
* added support for LOC_FPUREGISTER and LOC_MMREGISTER in several places
where they can now occur due to the previous two changes
* made a few internalerrors unique
