Load function types and arguments from DWARF when CFA and CFI information is used

[XVilka]

Support for applying correct offsets and sizes for variables and function returns given the CFI, CFA information from DWARF. Search for LOCATION_CFA

We also should expand testing by compiling the same float_ex1 for different architectures apart from ARM and Tricore:

• [ ] x86 (32bit)
• [ ] x86 (64bit)
• [ ] ARMv8
• [ ] MIPS
• [ ] SPARC
• [ ] PowerPC
• [ ] AVR

Probably different compilers and versions as well
