d8ff85846f * don't reuse mm registers used by child nodes

6a8e4f0381 * MIPS: generate real instructions, not macros, for comparisons with $zero. 
* g_concatcopy, g_concatcopy_unaligned: call a_cmp_reg_reg_label instead of duplicating code.

fb88cc4257 * TCGMIPS.a_load_reg_reg: reduce code duplication, and don't generate same register move for OS_32->OS_S32 and vice versa. Such moves explode into at least 4 instructions if register needs spilling, after which they are no longer recognized and cannot be removed by reg.allocator. So it's much better not to generate them in first place. 
* Implemented overflow checking for multiplication, no longer generate MULO and MULOU macros.

7e0ae2e984 * MIPS: fixed cgsize2subreg to return correct result for float registers. 
- TCGMIPS.getfpuregister override is no longer necessary with the above fix.

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

2e186a91fa Add support for integer constants to SetPEFlags and SetPEOptFlags. This is Delphi compatible. 
scandir.pas:
  + add function "get_peflag_const" to retrieve the value of a constant
  * dir_setpeflags & dir_setpeoptflags: first check for an identifier (value is retrieved through "get_peflag_const") and then read a value

+ added messages for illegal parameters for SetPEFlags and SetPEOptFlags respectively
+ added tests

511b1f37c1 * write the segment of aitconst_farptr on a separate line to avoid long symbol truncation, due to line length limit; this fixes compilation of sysutils in the medium memory model
