b2d5da9c43 Extend floating point precision in some tests 
These tests may work better with quadruple-presicion real types now.

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.

06037a25b4 std.math.exponential: Minimally relax a pow() unittest for targets with 64-bit real

8946209a9b Revert #7823 - Faster pow implementation for integral exponents 
There are multiple issues with that commit, incl. out-of-bounds read
on x86 systems and a significant performance decrease for qualified
floating-point types; see #8124 for a full list of flaws.

I'm questioning the tackled goal in the first place, because I expect
users to use that `pow` mainly with small integral exponents, *not*
expecting underflows to 0 or overflows to ±infinity, so optimizing
for these cases and sacrificing performance for the regular case doesn't
make a lot of sense to me.
