New Targets:

        . STM32L011x
            STM32L011x2
            STM32L011x4

        . STM32L021x4

        . STM32L432x
            STM32L432xB
            STM32L432xC

        . STM32L442xC

        . STM32F412x
            STM32F412xE
            STM32F412xG

Improvements:

        . C++: Call-stack displays method class names and parameters.
        . New version of GCC compiler, 5.4.1: optimizations.

Fixes:

        . C++: Don't display static class attributes in debugger watch windows.
        . STREX instruction wasn't correctly disassembled.
        . Changed status value in destination register for in STREX, STREXB and
          STREXH instruction from 0 (fail) to 1 (success).
        . ARM9 "BLX Reg" wasn't correctly supported leading to:
          - limited call-stack display.
          - issue with step-into.
        . STM32L0 debug with LowPower or Watchdog requires activating DBG clock
          in RCC.
        . Corrected STM32F030xC option byte configuration.
        . Option bytes "No action" configuration canceled: all projects set with
          this configuration will be automatically changed in "Restore Default"
        . Minor bugs fixes.

Limitations:

        . C++: Static attributes cannot be displayed in watch windows.
        . Open4-LAB does not support STM32L011 and STM32L432 devices in
          stand-alone mode.
