af235cae86 * use TEST CL,32 instead of TEST ECX,32 in the beginning of a 64-bit shl/shr 
sequence on i386

d7b8d8dd54 * don't emit the "SUB ECX,32" instruction on i386, when doing a 64-bit shift by 
reg, with a value >=32. The instruction is redundant, because the SHL/SHR
  instructions already AND mask the shift count by 31.

7e8c89435f * avoid the AND instruction in the i386 shr64/shl64 code, by using TEST+JZ, 
instead of CMP+JL

6580dfee39 * generate better i386 code for 64-bit shl/shr, by masking the shift count by 
63, instead of comparing it to 64 and branching. Note that, although this
  changes the behaviour of 64-bit shifts by values larger than 64 (when stored
  in a variable), it actually makes them consistent with both the code,
  generated on x86_64, as well as with 64-bit shift by constant on i386 itself.

92cf25b9a5 * Reworked i386 division by constant optimization to reuse code from powerpc64. The algorithm is slightly different, signed version is one instruction shorter, unsigned one is one instruction longer (typically). The new algorithm is easily scalable for x86_64 target, unlike the old one.

edd42aa42a * moved subsetref/reg and bit_set/test support from cgobj to hlcgobj for 
future use by high level code generator targets
   o this in turn required that all a_load*_loc* methods are called via
     hlcg rather than via cg, since a location can be a subsetref/reg and
     and those are no longer handled in tcg
   o that then required moving several force_location_* routines into
     thlcg because they use a_load_loc*, but did not take tdef size
     parameters (which are required by the thlcg a_load_loc* routines)
   o the only practical consequence is that from now on, you have to
     use hlcg.location_force_mem/reg() (fpureg not yet) and
     hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
     and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
     might be involved
