[X86] Fix a bug in the lowering of BLENDI introduced in r209043.
ISD::VSELECT mask uses 1 to identify the first argument and 0 to identify the
second argument.
On the other hand, BLENDI uses 0 to identify the first argument and 1 to
identify the second argument.
Fix the generation of the blend mask to account for this difference.
The bug did not show up with r209043, because we were not checking for the
actual arguments of the blend instruction!
This commit also fixes the test cases.
Note: The same mask works for the BLENDr variant because the arguments are
swapped during instruction selection (see the BLENDXXrr patterns).

Summary:
The minimal type needs to hold a value of '1ULL << 31' but
getMinimalTypeForRange() is called with a value of '1ULL << 32'.
This patch will also reduce the size of the matcher table when there are 8
or 16 SubtargetFeatures.
Also added a dump of the SubtargetFeatures to the -debug output and corrected getMinimalTypeInRange() to consider 0xffffffffull to be a 32-bit value.
The testcase is that no existing code is broken and that LLVM still successfully
compiles after adding MIPS64r6 CodeGen support.

ARM: correct bundle generation for MOV32T relocations
Although the previous code would construct a bundle and add the correct elements
to it, it would not finalise the bundle. This resulted in the InternalRead
markers not being added to the MachineOperands nor, more importantly, the
externally visible defs to the bundle itself. So, although the bundle was not
exposing the def, the generated code would be correct because there was no
optimisations being performed. When optimisations were enabled, the post
register allocator would kick in, and the hazard recognizer would reorder
operations around the load which would define the value being operated upon.
Rather than manually constructing the bundle, simply construct and finalise the
bundle via the finaliseBundle call after both MIs have been emitted. This
improves the code generation with optimisations where IMAGE_REL_ARM_MOV32T
relocations are emitted.
The changes to the other tests are the result of the bundle generation
preventing the scheduler from hoisting the moves across the loads. The net
effect of the generated code is equivalent, but, is much more identical to what
is actually being lowered.

[ARM64] PR19792: Fix cycle in DAG after performPostLD1Combine
Povray and dealII currently assert with "Overran sorted position" in
AssignTopologicalOrder. The problem is that performPostLD1Combine can
introduce cycles.
Consider:
(insert_vector_elt (INSERT_SUBREG undef,
(load (add %vreg0, Constant<8>), undef), <= A
TargetConstant<2>),
(load %vreg0, undef), <= B
Constant<1>)
This is turned into a LD1LANEpost node. However the address in A is not a
valid user of the post-incremented address of B in LD1LANEpost.

Unbreak the sanitizer buildbots after r209226 due to SROA issue described in reviews.llvm.org/D3714
Undecided whether this should include a test case - SROA produces bad
dbg.value metadata describing a value for a reference that is actually
the value of the thing the reference refers to. For now, loosening the
assert lets this not assert, but it's still bogus/wrong output...
If someone wants to tell me to add a test, I'm willing/able, just
undecided. Hopefully we'll get SROA fixed soon & we can tighten up this
assertion again.

[LSR] Canonicalize reg1 + ... + regN into reg1 + ... + 1*regN.
This commit introduces a canonical representation for the formulae.
Basically, as soon as a formula has more that one base register, the scaled
register field is used for one of them. The register put into the scaled
register is preferably a loop variant.
The commit refactors how the formulae are built in order to produce such
representation.
This yields a more accurate, but still perfectible, cost model.

GlobalValue: Testcase for hidden visibility and local linkage
This is a testcase for r209227, a change in LLVM that automatically sets
visibility to default when the linkage is changed to local (rather than
asserting).
What this testcase triggers is hard to reproduce otherwise: the
`GlobalValue` is created (with non-local linkage), the visibility is set
to hidden, and then the linkage is set to local.

GlobalValue: Automatically reset visibility when setting local linkage
r208264 started asserting in `setLinkage()` and `setVisibility()` that
visibility and linkage are compatible. There are a few places in clang
where visibility is set first, and then linkage later, so the assert
fires. In `setLinkage()`, it's clear what the visibility *should* be,
so rather than updating all the call sites just automatically fix the
visibility.
The testcase for this is for *clang*, so it'll follow separately in cfe.

Rewrite calculateDbgValueHistory to make it (hopefully) more transparent.
This change preserves the original algorithm of generating history
for user variables, but makes it more clear.
High-level description of algorithm:
Scan all the machine basic blocks and machine instructions in the order
they are emitted to the object file. Do the following:
1) If we see a DBG_VALUE instruction, add it to the history of the
corresponding user variable. Keep track of all user variables, whose
locations are described by a register.
2) If we see a regular instruction, look at all the registers it clobbers,
and terminate the location range for all variables described by these registers.
3) At the end of the basic block, terminate location ranges for all
user variables described by some register.
Although this change shouldn't be user-visible (the contents of .debug_loc section
should be the same), it changes some internal assumptions about the set
of instructions used to track the variable locations. Watching the bots.
