26689ac37e New approach to r136737: insert the necessary fences for atomic ops in platform-independent code, since a bunch of platforms (ARM, Mips, PPC, Alpha are the relevant targets here) need to do essentially the same thing. 
I think this completes the basic CodeGen for atomicrmw and cmpxchg.

0c9b559bfd Fix wrong usages of CTR/MCTR where CTR8/MCTR8 was meant. 
- Check for MTCTR8 in addition to MTCTR when looking up a hazard.

- When lowering an indirect call use CTR8 when targeting 64bit.

- Introduce BCTR8 that uses CTR8 and use it on 64bit when expanding ISD::BRIND.

The last change fixes PR8487. With those changes, we are able to compile a
running "ls" and "sh" on FreeBSD/PowerPC64.

68e6beeccc Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

1e61e69d40 add targetoperand flags for jump tables, constant pool and block address 
nodes to indicate when ha16/lo16 modifiers should be used.  This lets
us pass PowerPC/indirectbr.ll.

The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC.  I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Last major conversion item left is global variable references.

1e96bab329 In the calling convention logic, ValVT is always a legal type,

EVT is not needed.  Use MVT for ValVT everywhere.

1440e8b918 Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.
