[PATCH 0/7] Improve do_store_flag

[Andrew Pinski]

This patch set improves do_store_flag for the single bit case.
We go back to expanding the code directly rather than building some
trees. Plus instead of using shift+and we use directly bit_field
extraction; this improves code generation on avr.

Andrew Pinski (7):
  Move fold_single_bit_test to expr.cc from fold-const.cc
  Inline and simplify fold_single_bit_test_into_sign_test into
    fold_single_bit_test
  Use get_def_for_expr in fold_single_bit_test
  Simplify fold_single_bit_test slightly
  Simplify fold_single_bit_test with respect to code
  Use BIT_FIELD_REF inside fold_single_bit_test
  Expand directly for single bit test
