efd0c250df * fix for #39310 by fixing various small issues in tabstractrecordsymtable.has_single_field: 
- initialize the returned def to a safe default
  - correctly reset the found symbol for each loop
  - reset the result when descending into a record
+ added test

968d00fedf + Add support for -Adefault. 
* Move help message for option -sT to the correct group of messages. 
  * Use shorter message to indicate switch to external asm. 
  * Adapted -sX messages because -sT doesn't force external assembler writer.

07dcd22b1c * sizeof(array) and length(array) must return sizeUint in case the array 
size does not fit in sizeint. This fixes a range check error during
  compilation on small CPU targets where allowed array size is 64K, but
  sizeint is 32K max.

122ed4b76a * Support for sleb128 and uleb128 constants in the NASM writer. 
* Added sleb128tostr() and uleb128tostr() methods to TExternalAssembler.
* Use these methods in assembler writers instead of code duplication.

07698050e5 * Before r35961 (back in 2017) some simple assignment optimizations, such as "x:=x+y" to "inc(x,y)", were performed when -O2 in tassignmentnode.simplify. In r35961 these optimizations were moved to a separate pass which is enabled only when -O3 by cs_opt_use_load_modify_store. This separate pass can benefit from other optimization. But worse code is generated with -O2 since then. 
This commit restores applying of simple assignment optimizations when -O2.
