cf92bf760d Reimplement s_log1p.S and s_log1pf.S to use the fyl2xp1 instruction 
where necessary.

The log1p() function is provided to compute an accurate value of
log(1 + x), even for tiny values of x. The i387 FPU provides the
fyl2xp1 instruction for this purpose.

However, since the range of the fyl2xp1 function is limited to
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
          (-0.292893 <= x <= 0.414214)
we need to check if the argument is in the valid range.

In order to reduce the cost for testing the range, we only use
fyl2xp1 if the argument is in the range
               -0.25 <= x <= 0.25
which can be checked with just one conditional branch.

Fixes PR lib/22599 by Ray Brownrigg.

7e7bcf4bc9 Allow platforms to define __EH_FRAME_CONST. Currently "const" for x86_64, 
empty for others. x86_64 (and s390, which we do not have) have .eh_frame
as a read-only section, so __EH_FRAME_BEGIN__ and the register/deregister
functions must take a const foo *.

This also fixes an ICE in gcc 3.3.1 (see gcc PR #9552)

2194ee2027 Add a comment that explains that 
. this function cannot have _PROF_PROLOGUE
  . this function cannot be called via PLT

Change ENTRY to NENTRY for the former.

XXX: The latter is important in the gcc3 world, that have shared
libraries.  We will need to play tricks with .hidden to make sure
every shared library gets its own private __udivsi3 that it can call
directly, without going through the PLT.
