069fa51445 * use separate input and output files when invoking wlib to create a static 
library. This resolves a problem with parallel building of a i8086 cross
  compiler, due to a race condition in wlib, when running several instances of
  wlib in the same directory. The problem is in the way wlib creates a temp file
  in the current directory using non-atomic operations and with a high
  probability of a name collision. Using separate input and output files avoids
  this temp file creation by wlib.

ad301f8fa1 m68k: implemented t68kvecnode.update_reference_reg_packed. same as the generic one, but allocates int registers instead of address registers, because on 68k IMUL,SHR/SHL and AND can't work on address registers, which results in a lot of register shuffling

5ca1740bee Fix issue in is_thumb32_imm. imm<11:10> have to be non-zero meaning the rotate only works from 8 to 31. Caused 0x8000001F to be mistaken for a valid immediate.

258b42de26 m68k: added support for FSIN/FCOS. these are software supported on the 68040, so we should have a separate 68040/060 FPU option too, to avoid these in the future.

b617345e43 m68k: disabled premature MOVEA #0,Ax to SUBA Ax,Ax in the CG, because it breaks with spilling temp replacement and moved it to the optimizer, where it belongs. this fixes some code with potentially heavy address register pressure, like the IDE.

3d9713b9c8 * has_single_field() now looks recursively into fields that are aggregate 
types until it finds a non-aggregate type, and then returns "true" if
    that aggregate (record or array) contains one element
  * it now also returns the type of that element directly rather than a
    tfieldvarsym, since we only care about the type and in case of an array
    there is no field
