[ARM/FDPIC v6 14/24] [ARM][testsuite] FDPIC: Skip unsupported tests

Several tests cannot work on ARM-FDPIC for various reasons: skip them,
or skip some directives.

gcc.dg/20020312-2.c: Skip since it forces -fno-pic.

gcc.target/arm/:
* Skip since r9 is clobbered by assembly code:
  20051215-1.c
  mmx-1.c
  pr61948.c
  pr77933-1.c
  pr77933-2.c

* Skip since the test forces armv5te which is not supported by FDPIC:
  pr40887.c
  pr19599.c

* Skip since FDPIC disables sibcall to external functions:
  sibcall-1.c
  tail-long-call
  vfp-longcall-apcs

* Skip size check since it's different for FDPIC:
  ivopts-2.c
  ivopts-3.c
  ivopts-4.c
  ivopts-5.c
  pr43597.c
  pr43920-2.c

* Disable assembler scanning invalid for FDPIC:
  pr45701-1.c
  pr45701-2.c
  stack-red-zone.c

* gnu2 TLS dialect is not supported by FDPIC:
  tlscall.c

* Test relies on symbols not generated in FDPIC:
  data-rel-2.c
  data-rel-3.c
