+ added support for constructing target triplets
* pass "-target triplet" when using an LLVM assembler
o removed no longer needed $DARWINVERSION and $ARCH parameters
* consistently use as_clang_gas when clang is used to assembler GAS-style
assembly, and rename as_llcm_clang to as_clang_llvm (for consistency)
* support pipe assembling when using clang on *nix in all cases

* rename the m68k/PowerPC-MacOS targets to m68k/PowerPC-MacOSClassic
* repurpose the AArch64/Darwin target for AArch64/macOS
o make AArch64-Darwin default target for a hosted AArch64-Darwin compiler

private_extern (or plain global in case of PECOFF, as the effect is
the same there): visible across object files, but they become local
when linked into a binary/library. This enables cross-unit inlining
of functions accessig implementation-only symbols.

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)

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)

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

This unit was empty unless OLDREGVARS macro was set,
but this does not compile and no change has been made since 2011.
* Remove regvars from all _USES clauses.

procedure node_change_local_switch(p : tnode;cs : tlocalswitch;enable : boolean);
to add/remove cs local switch from all p tnode tree localsettings.
modify second_prefetch implementation in arm, ppcgen and x86 subdirectories
to use node_change_local_settings to temporarily disabled
checkpointer local switch, as prefetch is allowed even on unaccessible addresses.
(previous code was buggy because I frogot that each node has it own localswitches).
git-svn-id: trunk@34576 -
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
