bare-metal: Add IAR 8051 toolchain support

This commit adds a basic support of the IAR Embedded Workbench
toolchain for the 8051 processors family.

To use it with Qt Creator, it is enough to add there a desired Kit
with a custom IAR C/C++ compiler, and then set the following in the
Kit's Qbs profile settings:

* Key: qbs.toolchainType
* Value: iar

Tested with EW for 8051 v10.10.1 on Windows using the simple
projects samples which are comes with the default IAR installer.
