     i) CamelCase for methods, functions
    ii) snake_case for variables/structs
   iii) indentation (dont indent code inside namespace)

GNU ld has the INSERT option which makes the externally supported script not override the default script but insert the code into the default. The  new ld.implicit.script does just that and no modification to the default script is necessary anymore.

PROVIDE (_nodetext = .);
PROVIDE (nodetext = .);
INSERT BEFORE .text;

The tests were failing due to libgcc_s unwinder getting confused.
I was able to debug this problem and linking and using libunwind didnt have
any issues. The code MoveTextRegionToLargePages was being placed in eh_frame
region initially and this was causing the tests to fail.

I now create a new stub region (before .text) in the implicit script and
place the MoveTextRegionToLargePages in that region and also ensure
that this is ahead of the region we are moving.
