Remove old-GCC parts of x86 bits/mathinline.h.
In accordance with the general principle of preferring to let the compiler optimize function calls based on their standard semantics rather than putting inline definitions of such functions in installed headers, this patch removes various such inline definitions in the x86 bits/mathinline.h that were already disabled for GCC 3.5 or later and so were only used with very old compilers (for which good optimization is particularly unimportant); along with those inlines, a definition of __M_SQRT2, which was only used in such inline functions, is also removed. This is similar to an early step in removing the string.h inlines; I intend to follow up with further removals of bits/mathinline.h inline definitions in appropriate logical groups (with GCC bugs filed in cases where GCC doesn't already support corresponding optimizations). Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h [!__GNUC_PREREQ (3, 4)] (lrintf): Remove definitions used only with old GCC. [!__GNUC_PREREQ (3, 4)] (lrint): Likewise.
