[PowerPC] Rework TLS call operand processing

As part of the global-dynamic and local-dynamic TLS sequences, we need
to use a special form of the call instruction:

 bl __tls_get_addr(sym@tlsld)
 bl __tls_get_addr(sym@tlsgd)

which generates two fixups.  The current implementation of this causes
problems with recognizing this form in the asm parser.  To fix this,
this patch reworks operand processing for this special form by using
a single operand to hold both __tls_get_addr and sym@tlsld and defining
a print method to output the above form, and an encoding method to
generate the two fixups.

As a side simplification, the patch replaces the two instruction
patterns BL8_NOP_TLSGD and BL8_NOP_TLSLD by a single BL8_NOP_TLS,
since the patterns already operate in an identical fashion (whether
we have a local-dynamic or global-dynamic symbol is already encoded
in the symbol modifier).

To avoid this confusion, this patch removes the PowerPC-specific

 1. As discussed during review, it needs to be rewritten (to avoid creating and
then deleting instructions).

 2. This is causing optimizer crashes. Specifically, I'm seeing things like
this:

    While deleting: i1 %
    Use still stuck around after Def is destroyed:  <badref> = select i1 <badref>, i32 0, i32 1

   I'd guess that these will go away once we're no longer creating/deleting
instructions here, but just in case, I'm adding a regression test.

Because the code is bring rewritten, I've just XFAIL'd the original regression test. Original commit message:

InstCombine: Be more agressive optimizing 'udiv' instrs with 'select' denoms

Real world code sometimes has the denominator of a 'udiv' be a
'select'.  LLVM can handle such cases but only when the 'select'
operands are symmetric in structure (both select operands are a constant
power of two or a left shift, etc.).  This falls apart if we are dealt a
'udiv' where the code is not symetric or if the select operands lead us
to more select instructions.

Instead, we should treat the LHS and each select operand as a distinct
divide operation and try to optimize them independently.  If we can
to simplify each operation, then we can replace the 'udiv' with, say, a
'lshr' that has a new select with a bunch of new operands for the
select.
