[CostModel][x86] Improved cost model for alternate shuffles.

This patch:
 1) Improves the cost model for x86 alternate shuffles (originally
added at revision 211339);
 2) Teaches the Cost Model Analysis pass how to analyze alternate shuffles.

Alternate shuffles are a special kind of blend; on x86, we can often
easily lowered alternate shuffled into single blend
instruction (depending on the subtarget features).

The existing cost model didn't take into account subtarget features.
Also, it had a couple of "dead" entries for vector types that are never
legal (example: on x86 types v2i32 and v2f32 are not legal; those are
always either promoted or widened to 128-bit vector types).

The new x86 cost model takes into account what target features we have
before returning the shuffle cost (i.e. the number of instructions
after the blend is lowered/expanded).

This patch also teaches the Cost Model Analysis how to identify and analyze
alternate shuffles (i.e. 'SK_Alternate' shufflevector instructions):
 - added function 'isAlternateVectorMask';
 - added some logic to check if an instruction is a alternate shuffle and, in
   case, call the target specific TTI to get the corresponding shuffle cost;
 - added a test to verify the cost model analysis on alternate shuffles.

Fix ppcf128 component access on little-endian systems

The PowerPC 128-bit long double data type (ppcf128 in LLVM) is in fact a
pair of two doubles, where one is considered the "high" or
more-significant part, and the other is considered the "low" or
less-significant part.  When a ppcf128 value is stored in memory or a
register pair, the high part always comes first, i.e. at the lower
memory address or in the lower-numbered register, and the low part
always comes second.  This is true both on big-endian and little-endian
PowerPC systems.  (Similar to how with a complex number, the real part
always comes first and the imaginary part second, no matter the byte
order of the system.)

This was implemented incorrectly for little-endian systems in LLVM.
This commit fixes three related issues:

- When printing an immediate ppcf128 constant to assembler output
  in emitGlobalConstantFP, emit the high part first on both big-
  and little-endian systems.

- When lowering a ppcf128 type to a pair of f64 types in SelectionDAG
  (which is used e.g. when generating code to load an argument into a
  register pair), use correct low/high part ordering on little-endian
  systems.

- In a related issue, because lowering ppcf128 into a pair of f64 must
  operate differently from lowering an int128 into a pair of i64,
  bitcasts between ppcf128 and int128 must not be optimized away by the
  DAG combiner on little-endian systems, but must effect a word-swap.

lldb - problem with some PTRACE_* constants in NativeProcessLinux.cpp file

Change by Paul Paul Osmialowski

Today this is the only problem that I'm facing trying to cross-compile lldb for AArch64 using Linaro's toolchain.

PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS, PTRACE_SETFPREGS are not defined for AArch64
These things can be defined different ways for other architectures, e.g. for x86_64 Linux, asm/ptrace-abi.h defines them as preprocessor constants while sys/ptrace.h defines them in enum along with corresponding PT_* preprocessor constants
NativeProcessLinux.cpp includes sys/ptrace.h
To avoid accidental redefinition of enums with preprocessor constants, I'm proposing this patch which first checks for PT_* preprocessor constants then checks for PTRACE_* constants then when it still can not find them, it defines preprocessor constants.
Similar approach was already used for PTRACE_GETREGSET and PTRACE_SETREGSET constants; in this case however it was easier, since enum values in sys/ptrace.h and preprocessor constants shared all exactly the same names (e.g. there's no additional PT_GETREGSET name defined).

SGPRs are written by instructions that sometimes will ignore control flow,
which means if you have code like:

if (VGPR0) {
  SGPR0 = S_MOV_B32 0
} else {
  SGPR0 = S_MOV_B32 1
}

The value of SGPR0 will 1 no matter what the condition is.

In order to deal with this situation correctly, we need to view the
program as if it were a single basic block when we calculate the
live ranges for the SGPRs.  They way we actually update the live
range is by iterating over all of the segments in each LiveRange
object and setting the end of each segment equal to the start of
the next segment.  So a live range like:

[3888r,9312r:0)[10032B,10384B:0)  0@3888r

will become:

[3888r,10032B:0)[10032B,10384B:0)  0@3888r

This change will allow us to use SALU instructions within branches.
