attempt to load cyclic includes problem with avx2 load
sqrtm returns the same type as its input
fix bitfloating scalar cover test includes
adding missing NT2_TEST_BENCHMARK_DECL on symbols
remove undesired output from benchmarks, fix formatting, add missing include
Merge pull request #651 from MetaScale/avx2_load_fix

attempt to load cyclic includes problem with avx2 load
remove extra whitespace in bitinteger
parameter to gflops metric isn't actually used
missing include in f77_wrapper
formatting fixes in timing
demos: fix warnings, remove unnecessary cruft, re-arrange includes, fix some bad formatting
modifying ldexp in order for it to be consistent with frexp
change HPX initialization code so that HPX doesn't see argc/argv but the nt2 unit test system does
introduce meta::constant_value<Tag, T>. This meta-function returns the MPL integral constant associated with a constant. Use it instead of details::constant_type to generate constants
use meta::constant_value in ldexp to fix #644 + clean up scalar unit test
use vector_of to compute result type of constants instead of using same SIMD extension
Move args to test.unit
Adapt benchmarks to use unit_test and test_suite system
Factorize macros between test and benchs
Cosmetic fixes

- both bench and unit test display architecture correctly
- split each bench by a ----- line
- Made all ----- be 100 characters wide
