b6bfa864d4 Disallow the usage of the inline assembler inside generics, because there are currently two problems: 
1. At least on x86 the assembler reader initializes the parameter location informations which results in InternalError 200301231
2. Assembler tokens are not stored in the token stream and thus won't be reproduced during specialization

x86/rax86int.pas, tx86intreader.Assemble:
  * check for "parse_generic" before calling generate_parameter_info
pstatmnt.pas, assembler_block & statement:
  * generate an error message if an asm statement should be parsed inside a generic

+ added test

ec497ae11e + the regular tcgx86.a_call_name and .a_call_name_static moved to .a_call_name_near and .a_call_name_static_near, because a_call_name and a_call_name_static are going to be overriden in tcg8086
