91aa5feead Unify hypot and abs of complex values 
This ports the fixes from abs(T)(ComplexT) regarding NaN and skipping
potentially inaccuracy inducing mathematical no-ops when one arg is 0 to
hypot. Both functions do the same thing and should be deduplicated.
hypot also has some logic regarding under and overflows, and while I
don't fully understand it, it should probably not be removed for complex
numbers.

2e1f8de817 std.math.hardware: Fix broken IEEE FP flags tests 
1. The `pragma(inline, false)` doesn't do what the author thinks it does
   (Issue 23520).
2. Change that introduced `blockopt` seems to have a slight
   misunderstanding about what constant propagation is (`a /= 0.0L` can
   always be constant propagated regardless of what surrounds it).
3. Undocument tests that depend on the need for forcing operations to
   disarm the optimizer, and replace with simple tests behind StdDdoc.

std.math.trigonometry: fix tan asm x86 implementation for ldc compiler 
Somehow, separating asm blocks in small pieces produces additional
`mov`s and other instructions on LDC that breaks the tanAsm logic and
therefore returns wrong values.
