Adhemerval Zanella 76da726532 Fix ilogb exception and errno (bug 6794) 
[BZ #6794]
Following Joseph comments about bug 6794, here is a proposed fix. It turned out
to be a large fix mainly because I had to move some file along to follow libm
files/names conventions.

Basically I have added wrappers (w_ilogb.c, w_ilogbf.c, w_ilogbl.c) that now calls
the symbol '__ieee754_ilogb'. The wrappers checks for '__ieee754_ilogb' output and
set the errno and raise exceptions as expected.

The '__ieee754_ilogb' is implemented in sysdeps. I have moved the 's_ilogb[f|l]' files
to e_ilogb[f|l] and renamed the '__ilogb[f|l]' to '__ieee754_ilogb[f|l]'.

I also found out a bug in i386 and x86-64 assembly coded ilogb implementation where
it raises a FE_DIVBYZERO when argument is '0.0'. I corrected this issue as well.

Finally I added the errno and FE_INVALID tests for 0.0, NaN and +-InF argument. Tested
on i386, x86-64, ppc32 and ppc64.

Siddhesh Poyarekar 73d65cc378 New ld.so argument --inhibit-ldcache to disable ld.so.cache lookup 
It may sometimes be desirable to make the dynamic linker only pick up
libraries from the library path and rpath and not look at the
ld.so.cache that ldconfig generates. An example of such a use case is
the glibc testsuite where the dynamic linker must not be influenced by
any external paths or caches.

This change adds a new option --inhibit-ldcache that when used, tells
the dynamic linker to not use ld.so.cache even if it is available.

Michael Matz e80d6f94e1 Fix size parameter comparisions. 
[BZ #13592]
There are several signed compares of the size argument, whereas
it really is unsigned.  Depending on situations e.g. a "memset(ptr, 0,
-1)" segfault (but for the wrong reasons, because jumping into nirvana)
or succeeds even.

In normal use this is harmless, as a size with signbit set indicates
more than half the address space which on x86_64 is impossible to
allocate, but as the size is used to index some jump tables this
potentially could have other unwanted side effects.

Liubov Dmitrieva 4b43400f6a optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.S 
I've improved the following implementation of memcpy:
"sysdeps/i386/i686/multiarch/memcpy-ssse3.S".

The patch includes some minor style fixes, but the important part is
just using prefetch loops for the case:

DATA_CACHE_SIZE_HALF <= len <  SHARED_CACHE_SIZE_HALF and
src and dst pointers have unequal 16 byte alignments.

This gives from 6% - 50% performance boost on the atom machine, about
24,73% in geometric mean.
