Rename PowerPC64 pcrel GOT TLS relocations
These relocations should have had REL in their names, to reflect the
fact that they are pc-relative. Fix that now by adding _PCREL.
I've added some back-compatibility code to support anyone using
.reloc with the old relocations.

gold: x86-64: Fix TLSDESC relaxation for x32
X32 TLSDESC sequences can be:
40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg
...
67 ff 10 call *foo@TLSCALL(%eax)
or the same sequence as LP64:
48 8d 05 00 00 00 00 lea foo@TLSDESC(%rip), %reg
...
ff 10 call *foo@TLSCALL(%rax)
We need to support both sequences for x32. For both GDesc -> IE/LE
transitions,
67 ff 10 call *foo@TLSCALL(%eax)
should relaxed to
0f 1f 00 nopl (%rax)
For GDesc -> LE transition,
40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg
should relaxed to
40 c7 c0 fc ff ff ff rex movl $foo@tpoff, %reg
For GDesc -> IE transition,
40 8d 05 00 00 00 00 rex lea foo@TLSDESC(%rip), %reg
should relaxed to
40 8b 05 00 00 00 00 rex movl foo@gottpoff(%rip), %eax
