target-tricore: Add FPU infrastructure

Browse source 
This patch adds a file for all the FPU related helpers with all the includes,
useful defines, and a function to update the status bits. Additionally it adds
a mask for the rounding mode bits of PSW as well as all the opcodes for the
FPU instructions.
