70ae0d2851 Use secp256k1_fe_equal_var in secp256k1_fe_sqrt_var. 
In theory this should be faster, since secp256k1_fe_equal_var is able to
 shortcut the normalization.  On x86_64 the improvement appears to be in
 the noise for me.  At least it makes the code cleaner.

9ab93355f2 Add a reference consistency test to ge_tests. 
This adds all points used in the test together in random order, which
should result in infinity.

Suggested by Greg Maxwell.

1f46b006b7 build: fix __builtin_expect detection for clang 
Using AC_CHECK_DECL, the generated test tries to cast the function to void.
Clang doesn't allow that for builtins.
