Implement the following instructions: * `RotateLeft` (`RL`) * `RotateRight` (`RR`) * `RotateLeftByte` (`RLB`) * `RotateRightByte` (`RRB`) * `ShiftLeft` (`SL`) * `ShiftRight` (`SR`) * `ShiftLeftByte` (`SLB`) * `ShiftRightByte` (`SRB`) * `ArithmeticShiftRight` (`ASR`) DB48X adds counted variants of the above, that shift by an amount other than one or eight. * `RotateLeftCount` (`RLC`), rotating left several bits * `RotateRightCount` (`RRC`), rotating right several bits * `ShiftLeftCount` (`SLC`), shift left several bits * `ShiftRightCount` (`SRC`), shift right several bits * `ArithmeticShiftRightCount` (`ASRC`), arithmetic shift right several bits Also slight rework of the `BasesMenu`. Fixes: #622 Signed-off-by: Christophe de Dinechin <christophe@dinechin.org>

This release was a bit longer in coming than earlier ones, because we are about to reach the limits of what can fit on a DM42. This release uses 711228 bytes out of the 716800 (99.2%). Without the Intel Decimal Library code, we use only 282980 bytes. This means that the Intel Decimal Library code uses 60.2% of the total code space. Being able to move further requires a rather radical rethinking of the project, where we replace the Intel Decimal Library with size-optimized decimal code. As a result, release 0.5.2 will be the last one using the Intel Decimal Library, and is release in parallel with 0.6.0, which switches to a table-free and variable-precisions implementation of decimal code that uses much less code space. The two releases should otherwise be functionally identical **New features** * Shift and rotate instructions (#622) * Add `CompatibleTypes` and `DetsailedTypes` setting to control `Type` results * Recognize HP-compatible negative values for flags, e.g. `-64 SF` (#625) * Add settings to control multiline result and stack display (#634) **Bug fixes** * Truncate to `WordSize` the small results of binary operations (#624) * Fix day-of-week shortcut in simulator * Avoid double-evaluation of immediate commands when there is no help * Generate an error when selecting base 1 (#628) * Avoid `Number too big` error on based nunbers * Correctly garbage-collect menu entries (#630) * Select default settings that allow solver to find solutions (#627) * Fix display of decimal numbers (broken by multi-line display) * Fix rendering of menu entries for `Fix`, `Std`, etc * Detect non-finite results in arithmetic, e.g. `(-8)^0.3`m (#635, #639) * Fix range-checking for `Dig` to allow `-1` value * Accept large values for `Fix`, `Sci` and `Eng` (for variable precision) * Restore missing last entry in built-in units menu (#638) * Accept `Hz` and non-primary units as input for `ConvertToUnitPrefix` (#640) * Fix LEB128 encoding for signed value 64 and similar (#642) * Do not parse `IfThenElse` as a command * Do not consider `E` as a digit in decimal numbers (#643) * Do not parse `min` as a function in units, but as minute (#644) **Improvements** * Add `OnesComplement` flag for binary operation (not used yet) * Add `ComplexResults` (-103) flag (not used yet) * Accept negative values for `B→R` (according to `WordSize`) * Add documentation for `STO` and `RCL` accessing flash storage * Mention `True` and `False` in documentation * Rename `MaxBigNumBits` to `MaxNumberBits` * Return HP-compatible values from `Type` function * Minor optimization of flags implementation * Catalog auto-completion now suggests all possible spellings (#626) * Add aliases for `CubeRoot` and `Hypothenuse` * Align based number promotion rules to HP calculators (#629) * Expand the range of garbage collector integrity check on simulator * Show command according to preferences in error messages (#633) * Avoid crash in `debug_printf` if used before font initialization * Update performance data in documentation * Add ability to disable any reference to Intel Decimal Floating-point library * Simplify C++ notations for safe pointers (`+x` and `operartor bool()`) * Fix link to old `db48x` project in `README.md` Signed-off-by: Christophe de Dinechin <christophe@dinechin.org>
