[PATCH 1/5] ARM Intrinsics Support

[Stephen Thomas]

This patch changes the way producer/consumer scheduling relationships
between
pairs of RTL fragments are detected to work in a more general way. This is
necessary because some of the new intrinsics introduce RTL patterns of a
form the original detection code did not expect to encounter.

This has been tested as a part of testing this series of patches as a
whole and does not show any extra regressions. Tested for ARMv7-a/Thumb2
on qemu for arm-none-eabi on trunk with no extra regressions. Testing for
ARMv4t for arm-none-eabi in progress. OK to commit?
