Hello,

Please find a set of two patches that adds stack backtracing support
for the new SFrame V3.

The first patch is adding support for default FDEs by changing the
reading functions in sframe-read.c and sframe.c files.

The second patch is adding support for the new FLEX FDEs. The FLEX
FDEs are enabled when CFI [atterns require it and target hooks allow
it. This patch adds the necessary bits for implementing it for x86_64
and aarch64 targets. A new test is added too.

Best wishes,
Claudiu
