67bf76c50e - Fix overflow checking in software multiplication routines. Overflow checking should also be enabled for the unsigned multiplications. 
- Call FPC_Overflow instead of multiple calls to save on size.

ff020a3be4 + "Utf8CodePointLen(pansichar,MaxLookAhead,IncludeCombiningDiacriticalMarks): 
sizeint"  function that returns:
   <0: invalid sequence detected after processing "-result" bytes
   0:  incomplete (may still be valid if MaxLookAhead is increased)
   >0: sequence of result bytes forms a codepoint (+ combining diacritical
       marks if that parameter was true)

98332db7fe * Improved generic implementations of Bsf/Bsr. Existing ones were just ugly, BsfQword/BsrQWord producing total of 15 inline expansions 5 levels down and bloating into just a little less than a kilobyte of code (on MIPS). Now it is at most 3 expansions and 21 instructions (84 bytes), 16 and 32 bit routines are branchless.

217ab9879c * Enabled internal handling of Abs(longint) for all targets. It has been implemented in cross-platform way ages ago (see tcginlinenode.second_abs_long), but not enabled on MIPS,SPARC and m68k. 
- RTL: removed MIPS,SPARC and m68k-specific implementations of Abs(longint), and marked the generic one as  required for bootstrapping purposes only.

94a045aa3d * Moved declarations of TFPURoundingMode,TFPUExceptionMask and TFPUPrecisionMode to System unit. Declarations in Math unit changed to aliases. 
* Changed type of softfloat_exception_mask and softfloat_exception_flags to TFPUExceptionMask, softfloat_rounding_mode to TFPURoundingMode.

1626667374 * Object helper routines review/improvement for alignment-sensitive targets: 
- Replaced duplicate local declarations of pvmt/tvmt with pobjectvmt/tobjectvmt
    (name change needed because tvmt is already used for class-style VMTs)
  - Removed 'packed' attribute from tobjectvmt, since it is always aligned.
  * Use appropriate typecasts to generate aligned memory accesses where possible.

690995fa12 * RTL: fixed some warnings when compiling for x86_64: 
* x86_64/x86_64.inc: IsMultithread is a LongBool, not Boolean -> fixed assembler instruction suffixes
  * inc/generic.inc: cast Sizeof() to unsigned, so that combining it with unsigned operands does not cause promotion to larger signed type.
  + win64/seh64.inc: explicit typecast and missing function result assignment.
  + inc/genmath.inc: explicit typecasts.
