Second part of patches submitted in the v3.

This series adds a subset of single precision and
double precision instructions using
set_floatx80_rounding_precision() to round the result.

For some other instructions, we introduce a new
function, floatx80_round(), to round them manually.

It also adds instructions fsglmul, fsgldiv,
fmovecr and fscc (since v3, use tcg_gen_setcond())

fmovem manages static and dynamic register list,
all the code has been moved to an helper.

v4:
  Update floatx80_round() comment (and add Aurélien's R-b)
  Add a comment for undefined fmovecr offsets
  update gen_fcc_cond() with more fixes from Richard

v3:
  Remove extra space in fmovem patch
  truncate operands of fsglmul and fslgdiv
  update gen_fcc_cond() as suggested by Richard
  fmoverc: use opmode instead of rom_offset,
  define and free the tcg constant

v2:
  Fix gen_fcc_cond(): g[12] mark global variables,
  not variables to free.
  add 2 patches to compute trigonometric functions
  and fmod
  use floatx80_round() to compute fsglmul and fsgldiv
  split fmovem helper into 6 helpers

Laurent Vivier (7):
  target/m68k: add fscc.
  target/m68k: add fmovecr
  target/m68k: add explicit single and double precision operations
  softfloat: define floatx80_round()
  target/m68k: add fsglmul and fsgldiv
  target/m68k: add explicit single and double precision operations (part
    2)
  target/m68k: add fmovem
