Fix for BUG #11642: [Patch]es x86 Assembler and text relocations

Changed assembler functions to not access global variables or variables in text segement
Added wrapper function in C to longlong2str() to pass _dig_vec_upper as an argument


mysql-test/r/bigint.result:
  More tests for parsing of bigint's
  More tests for different values to conv()
mysql-test/t/bigint.test:
  More tests for parsing of bigint's
  More tests for different values to conv()
strings/Makefile.am:
  Added longlong2str_asm.c
strings/longlong2str-x86.s:
  Changed functions to not access variables in text segment
  Fixed this by adding global variable '_dig_vec_upper' as an argument to longlong2str_with_dig_vector()
strings/my_strtoll10-x86.s:
  Removd array lfactor by calculating the value in code
  (this is to to make the code position independent)
strings/longlong2str_asm.c:
  New BitKeeper file ``strings/longlong2str_asm.c''
