o ensure that for AArch64, "struct return" the parameter always is the first
parameter, as it needs to be returned in a special register there

how the fpc sections have to be linked *on Linux*. This prevents the
"did you forget -T" warnings from ld, and in general is more correct than
our previous approach of specifying a complete linker script without -T
and hoping that there won't be any unexpected interactions with ld's
built-in linker script (fixed version of r31664, thanks to Alan Modra)
o use the new -X9 command line option to generate linker scripts that
are compatible with binutils older than 2.19 (reverts to the old
behaviour)

(they were not functional, but now cause internalerrors due to
invocations of the high level typed constant builder rather than their
output gets ignored)

o there are llvm intrinsics for all of these except for atan,
but these obey "the same rules as the equivalent libc functions"
and I first have to investigate whether these libc functions
behave the same as our FPC implementations

the number of elements in case that number is only known afterwards

right now, so give an internalerror if something else is passed
* use the correct type when emitting a resourcestring like that (it will store
the address of the resource string -> pointer to an ansistring)

o this allows us to write the VMTs earlier (before the synthetic method
implementations are generated), which means we can create new synthetic
methods while generating the VMTs (for interface trampolines)

* write the code for pure assembler routines using a GNU-style external
assembler writer for the target, with a decorator to wrap it in
LLVM module-level assembly statements

from the bind of the tasmsymbol. The reason is that with module-level
inline assembly, some locally implemented functions (in pure assembler)
won't have an LLVM IR body

that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
