[PowerPC] Simplify and improve loading into TOC register

During an indirect function call sequence on the 64-bit SVR4 ABI,
generate code must load and then restore the TOC register.

This does not use a regular LOAD instruction since the TOC
register r2 is marked as reserved.  Instead, the are two
special instruction patterns:

 let RST = 2, DS = 2 in
 def LDinto_toc: DSForm_1a<58, 0, (outs), (ins g8rc:$reg),
                     "ld 2, 8($reg)", IIC_LdStLD,
                     [(PPCload_toc i64:$reg)]>, isPPC64;

 let RST = 2, DS = 10, RA = 1 in
 def LDtoc_restore : DSForm_1a<58, 0, (outs), (ins),
                     "ld 2, 40(1)", IIC_LdStLD,
                     [(PPCtoc_restore)]>, isPPC64;

Note that these not only restrict the destination of the
load to r2, but they also restrict the *source* of the
load to particular address combinations.  The latter is
a problem when we want to support the ELFv2 ABI, since
there the TOC save slot is no longer at 40(1).

This patch replaces those two instructions with a single
instruction pattern that only hard-codes r2 as destination,
but supports generic addresses as source.  This will allow
supporting the ELFv2 ABI, and also helps generate more
efficient code for calls to absolute addresses (allowing
simplification of the ppc64-calls.ll test case).

[PowerPC] Do not use BLA with the 64-bit SVR4 ABI

The PowerPC back-end uses BLA to implement calls to functions at
known-constant addresses, which is apparently used for certain
system routines on Darwin.

However, with the 64-bit SVR4 ABI, this is actually incorrect.
An immediate function pointer value on this platform is not
directly usable as a target address for BLA:
- in the ELFv1 ABI, the function pointer value refers to the
  *function descriptor*, not the code address
- in the ELFv2 ABI, the function pointer value refers to the
  global entry point, but BL(A) would only be correct when
  calling the *local* entry point

This bug didn't show up since using immediate function pointer
values is not usually done in the 64-bit SVR4 ABI in the first
place.  However, I ran into this issue with a certain use case
of LLVM as JIT, where immediate function pointer values were
uses to implement callbacks from JITted code to helpers in
statically compiled code.

Fixed by simply not using BLA with the 64-bit SVR4 ABI.
