12b2f86e99 + added function requires_fwait_on_8087(), which checks whether a given 
instruction needs adding a FWAIT prefix on the i8087.

d0f988f7a8 * don't use LEA in the code generator on i8086, as this breaks it quite badly. 
While it is possible to use 16-bit LEA on the i8086, it's probably not worth
  doing it in the code generator, because of the unpleasant register
  restrictions that 16-bit references have.

486a7ef81e * tx86inlinenode.second_popcnt: use emit_ref_reg instead of appending instruction directly, this provides proper PIC handling of the reference. emit_reg_reg part is not strictly necessary, but done for consistency.

0f69362edd - rm LEA reg,imm from x86ins.dat, as that's not a valid x86 instruction, 
using it in inline asm causes an internal error and removing it didn't show

5af873ee5b * x86 targets: Profiling shows that quite a bit of time is spent in findreg_by_number(), despite it uses binary search. Worse, it is repeated for every piece of register information. Trying to get rid of some of these calls: rearranged registers so that their "opcode" matches 3 LSBs of superregister number (with a few exceptions described at the beginning of x86reg.dat). This allows to lookup opcodes in regval() with O(1) complexity, and removes need in rXXXop.inc files.

5c4abfa75a + Implemented saving/restoring registers using PUSH/POP instructions on i386 targets with non-fixed stack. Provides some advantage in code size (e.g. the compiler becomes about 20KBytes smaller). 
* This should be applicable to i8086 targets as well (but needs testing), by copying changes from i386/cgcpu.pas to i8086/cgcpu.pas and removing "$ifdef i386" lines in cgx86.pas.

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
