  This patch set adds support for SFrame version 2.

The main change in SFrame version 2 is in the representation of the SFrame
Function Description Entry - it is now of size 20 bytes making each element
aligned at their natural boundary.

These commits are broken down into small chunks for ease of review only.  The
commits touching sframe.h, gas implementation, ld changes, and readelf/objdump
changes will need to be squashed into a single patch for an upstream commit.

Similarly, the doc updates can be squashed into one.

I would like to commit these by Thursday June 29 ideally.

Thanks,

  sframe.h: format bump to SFrame version 2
  gas: generate SFrame section with version SFRAME_VERSION_2
