[libstdc++-v3] Collapse redundant 'inline' from 'inline constexpr'.

[Ed Smith-Rowland]

All,

Paolo Carlini pointed out that I introduced a number of 'inline 
constexpr' in my last std literals patch.
Section 7.1.5/2: "constexpr functions and constexpr constructors are 
implicitly inline (7.1.2).

I noticed that there are two other headers that have this.

Does anyone mind if i just clean this up?

Builds and tests clean on x86_64-linux.
