AMDGPU/SI: Select constant loads with non-uniform addresses to MUBUF instructions
Summary:
We were previously selecting all constant loads to SMRD instructions and legalizing
the SMRDs with non-uniform addresses during the SIFixSGPRCopesPass.
This new solution is more simple and also generates much better code, because
the instruction selector is able to take advantage of all the MUBUF addressing
modes that are legalization pass wasn't able to.
We also no longer need to generate v_add_* instructions when we
have a uniform pointer and a non-uniform offset, as this is now folded into the
MUBUF instruction during instruction selection.

LPM: Stop threading `Pass *` through all of the loop utility APIs. NFC
A large number of loop utility functions take a `Pass *` and reach
into it to find out which analyses to preserve. There are a number of
problems with this:
- The APIs have access to pretty well any Pass state they want, so
it's hard to tell what they may or may not do.
- Other APIs have copied these and pass around a `Pass *` even though
they don't even use it. Some of these just hand a nullptr to the API
since the callers don't even have a pass available.
- Passes in the new pass manager don't work like the current ones, so
the APIs can't be used as is there.
Instead, we should explicitly thread the analysis results that we
actually care about through these APIs. This is both simpler and more
reusable.

[SimplifyCFG] allow speculation of exactly one expensive instruction (PR24818)
This is the last general step to allow more IR-level speculation with a safety harness in place in CodeGenPrepare.
The intent is to restore the behavior enabled by:
http://reviews.llvm.org/rL228826
but prevent bad performance such as:
https://llvm.org/bugs/show_bug.cgi?id=24818
Earlier patches in this sequence:
D12882 (disable SimplifyCFG speculation for expensive instructions)
D13297 (have CGP despeculate expensive ops)
D14630 (have CGP despeculate special versions of cttz/ctlz)
As shown in the test cases, we only have two instructions currently affected: ctz for some x86 and fdiv generally.
Allowing exactly one expensive instruction is a bit of a hack, but it lines up with what is currently implemented
in CGP. If we make the despeculation more general in CGP, we can make the speculation here more liberal.
A follow-up patch will adjust the cost for sqrt and possibly other typically expensive math intrinsics (currently
everything is cheap by default). GPU targets would likely want to override those expensive default costs (just as
they probably should already override the cost of div/rem) because just about any math is cheaper than control-flow
on those targets.

Weights are specified by using the --weighted-input=<weight>,<filename> option. Input files not specified
with this option (normal positional list after options) are given a default weight of 1.
Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the

This patch does two things:
1. mem2reg is now run immediately after globalopt. Now that globalopt
can localize variables more aggressively, it makes sense to lower
them to SSA form earlier rather than later so they can benefit from
the full set of optimization passes.
2. More scalar optimizations are run after the loop optimizations in
LTO mode. The loop optimizations (especially indvars) can clean up
scalar code sufficiently to make it worthwhile running more scalar
passes. I've particularly added SCCP here as it isn't run anywhere
else in the LTO pass pipeline.
Mem2reg is super cheap and shouldn't affect compilation time at all. The
rest of the added passes are in the LTO pipeline only so doesn't affect
the vast majority of compilations, just the link step.

Instcombine: destructor loads of structs that do not contains padding
For non padded structs, we can just proceed and deaggregate them.
We don't want ot do this when there is padding in the struct as to not
lose information about this padding (the subsequents passes would then
try hard to preserve the padding, which is undesirable).
Also update extractvalue.ll and cast.ll so that they use structs with padding.
Remove the FIXME in the extractvalue of laod case as the non padded case is
handled when processing the load, and we don't want to do it on the padded
case.

add fast-math-flags to 'call' instructions (PR21290)
This patch adds optional fast-math-flags (the same that apply to fmul/fadd/fsub/fdiv/frem/fcmp)
to call instructions in IR. Follow-up patches would use these flags in LibCallSimplifier, add
support to clang, and extend FMF to the DAG for calls.
Motivating example:
%y = fmul fast float %x, %x
%z = tail call float @sqrtf(float %y)
We'd like to be able to optimize sqrt(x*x) into fabs(x). We do this today using a function-wide
attribute for unsafe-math, but we really want to trigger on the instructions themselves:
%z = tail call fast float @sqrtf(float %y)
because in an LTO build it's possible that calls with fast semantics have been inlined into a
function with non-fast semantics.

[IR] Remove terminatepad
It turns out that terminatepad gives little benefit over a cleanuppad
which calls the termination function. This is not sufficient to
implement fully generic filters but MSVC doesn't support them which
makes terminatepad a little over-designed.
Depends on D15478.

FastISel needs to remove dead code when it bails out.
When FastISel fails to translate an instruction it hands off code
generation to SelectionDAG. Before it does so, it may have generated
local value instructions to feed phi nodes in successor blocks. These
instructions will then be generated again by SelectionDAG, causing
duplication and less efficient code, including extra spill
instructions.

[InstCombine] fold trunc ([lshr] (bitcast vector) ) --> extractelement (PR25543)
This is a fix for PR25543:
https://llvm.org/bugs/show_bug.cgi?id=25543
The idea is to take the existing fold of:
bitcast ( trunc ( lshr ( bitcast X))) --> extractelement (bitcast X)
( http://reviews.llvm.org/rL112232 )
And break it into less specific transforms so we'll catch more cases such as
the example in the bug report:
bitcast ( trunc ( lshr ( bitcast X))) -->
bitcast ( extractelement (bitcast X)) -->
extractelement (bitcast X)
Enabling patches for this change:
http://reviews.llvm.org/rL255399 (combine bitcasts)
http://reviews.llvm.org/rL255433 (canonicalize extractelement(bitcast X))

Don't create unnecessary PHIs
In conditional store merging, we were creating PHIs when we didn't
need to. If the value to be predicated isn't defined in the block
we're predicating, then it doesn't need a PHI at all (because we only
deal with triangles and diamonds, any value not in the predicated BB
must dominate the predicated BB).
This fixes a large code size increase in some benchmarks in a popular embedded benchmark suite.
