r21885 added a new peephole optimizer. The associated code refactoring
missed a check for
tai(hp1).typ = tai_instruction
Which can lead to an access violation later on, because the rest of the
code expects to find a taicpu in hp1.

(tf_safecall_clearstack is set for it) -> also use pocalls_cdecl for it
and adjust the safecall tests not to try parameter scenarios that are
unsupported for cdecl

order to minimise memory losses due to alignment padding. Not yet enabled
by default at any optimization level, but can be (de)activated separately
via -Oo(no)orderfields
o added separate tdef.structalignment method that returns the alignment
of a type when it appears in a record/object/class (factors out
AIX-specific double alignment in structs)
o changed the handling of the offset of a delegate interface
implemented via a field, by taking the field offset on demand
rather than at declaration time (because the ordering optimization
causes the offsets of fields to be unknown until the entire
declaration has been parsed)

overflow (don't know what the y-coordinate is at that point, because the
window may be wider than the artificial screenwidth) (mantis #20880)

after all, although for some reason the problems only showed up with the
external assembler on x86-64 platforms other than Darwin. Now we never use
GOT entries on x86-64 anymore for local symbols, regardless of their nature,
and instead use plain RIP-relative addressing for them.

the drawback of this is that get_caller_frame and get_caller_addr might not work
anymore because they make the wrong assumption (i.e. not required by the abi)
that ebp contains always a valid (not necessarily the current) frame pointer

Like MOV these instructions support 2 operands, with the second beeing a
shifterop.
Without this patch the asm reader would fail on something like
cmp r0, r1, lsr 16
with
Error: Unknown identifier "LSR"

used across multiple levels of inheritance such as on MIPS (and the code
has to be reusable for a_call_ref/reeg in the future anyway)
git-svn-id: trunk@21906 -
defines INTERNAL_BACKTRACE (which assumes get_frame to be internal rather
than a system unit procedure)
* changed fpc_assert() declaration for jvm to be the same as for other
targets, so the same code can be used to call it in ninl now that's
called from the first pass
