The asm code has high maintainance cost.
The cost is extremely high if we take into
consideration time64 implementation which implies
operating with 64bit numbers on 32bit system.
Also glibc uses mainly C in NPTL code.

This matches a similar change made to glibc.
No functional changes here.

The libc stubs should never override the libpthread provided
functions inside libpthread, otherwise the struct pthread_functions
that is used by the forwarder stubs goes bad.

This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e.
Marking the symbols hidden is wrong, because libc accesses
the pthreads internal symbols for internal locking.

Add attribute_hidden to all symbols having libc forwarder. This prevents
recursive self calls which would happen if libc is before libpthread in
linking order: the forwarder functions would call itself via the function
table, since the libpthread symbols would get overwritten with libc ones.
This has not been a problem in glibc since there these symbols are marked
hidden with linker version-script. Since we don't use one, we need to mark
these explicitly.
