The reversion apparently deleted the test/Transforms directory.
Will be re-reverting again.

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Revert r301950: SpeculativeExecution: Stop using whitelist for costs2017-05-10T12:30:07+00:00Chandler Carruthchandlerc@gmail.com2017-05-10T12:30:07+00:00urn:sha1:f3bd8ddedb7f5641d16b15af8b7b327ae5cbf10b
This pass doesn't correctly handle testing for when it is legal to hoist
arbitrary instructions. The whitelist happens to make it safe, so before
it is removed the pass's legality checks will need to be enhanced.
Details have been added to the code review thread for the patch.

SpeculativeExecution: Stop using whitelist for costs2017-05-02T18:02:18+00:00Matt ArsenaultMatthew.Arsenault@amd.com2017-05-02T18:02:18+00:00urn:sha1:9ac7d6be3c4a3426d4b0a0f75a1d27f80d6ed304
Just let TTI's cost do this instead of arbitrarily restricting
this.

Partial step towards removing the whitelist and only
using TTI's cost.

Move divergent-target test into CodeGen/NVPTX because it requires an NVPTX target.2016-04-15T01:20:52+00:00Justin Lebarjlebar@google.com2016-04-15T01:20:52+00:00urn:sha1:f04e678e36f9cc1755f6e797f7b8a322d8cd4acc

[Speculation] Add a SpeculativeExecution mode where the pass does nothing unless TTI::hasBranchDivergence() is true.2016-04-15T00:32:09+00:00Justin Lebarjlebar@google.com2016-04-15T00:32:09+00:00urn:sha1:cad81cf6b3032d9956f4e772431bb499a74a9ddb
Summary:
This lets us add this pass to the IR pass manager unconditionally; it
will simply not do anything on targets without branch divergence.

Add a speculative execution pass2015-05-15T17:54:48+00:00Jingyue Wujingyue@google.com2015-05-15T17:54:48+00:00urn:sha1:154eb5aa1d9c829715d13c9a047d4498be4d2e2a
Summary:
This is a pass for speculative execution of instructions for simple if-then (triangle) control flow. It's aimed at GPUs, but could perhaps be used in other contexts. Enabling this pass gives us a 1.0% geomean improvement on Google benchmark suites, with one benchmark improving 33%.
Credit goes to Jingyue Wu for writing an earlier version of this pass.
Patched by Bjarke Roune.
Test Plan:
This patch adds a set of tests in test/Transforms/SpeculativeExecution/spec.ll
The pass is controlled by a flag which defaults to having the pass not run.
