0dfec56734 Gold-plugin: Broaden scope of get/release_input_file to scope of Module.
Summary:
Move calls to get_input_file and release_input_file out of
getModuleForFile(). Otherwise release_input_file may end up
unmapping a view of the file while the view is still being
used by the Module (on 32-bit hosts).

Fix for PR22482.

Test Plan: Add test using --no-map-whole-files.

fc58cf7676 Fix SelectionDAG compile time issue with alias analysis.
Add new token factor node and its users to worklist if alias analysis is
turned on, in DAGCombiner::visitTokenFactor(). Alias analysis may cause
a lot of new token factors to be inserted into the DAG, and they need to
be optimized to avoid significant slow-downs.

c0021e43ea R600/SI: Enable a lot of existing tests for VI (squashed commits)
This is a union of these commits:

* R600/SI: Enable more tests for VI which need no changes

* R600/SI: Enable V_BCNT tests for VI
    Differences:
    - v_bcnt_..._e32 -> _e64
    - s_load_dword* inline offset is in bytes instead of dwords

* R600/SI: Enable all tests for VI which use S_LOAD_DWORD
    The inline offset is changed from dwords to bytes.

* R600/SI: Enable LDS tests for VI
    Differences:
    - the s_load_dword inline offset changed from dwords to bytes
    - the tests checked very little on CI, so they have been fixed to check all
      instructions that "SI" checked

* R600/SI: Enable lshr tests for VI

* R600/SI: Fix divrem64 tests
    - "v_lshl_64" was missing "b" before "64"
    - added VI-NOT checks

* R600/SI: Enable the SI.tid test for VI

* R600/SI: Enable the frem test for VI
    Also, the frem_f64 checking is added for CI-VI.

* R600/SI: Add VI tests for rsq.clamped

f033db57e9 [TTI] Improved cost heuristic for cttz/ctlz calls.
This patch is a follow-up of r228826 (see code-review: D7506).

Now that SimplifyCFG uses TargetTransformInfo for cost analysis, we 
have to fix the cost heuristic for intrinsic calls to cttz/ctlz.

This patch defines method 'getIntrinsicCost' in BasicTTIImpl: now, BasicTTIImpl
queries TLI to check if a call to cttz/ctlz is cheap for the target.

Added test cases in Transforms/SimplifyCFG/X86 to verify that on x86,
SimplifyCFG only speculates a call to cttz/ctlz if it is cheap.

4de471dd0a [SimplifyCFG] Swap to using TargetTransformInfo for cost
analysis.

We're already using TTI in SimplifyCFG, so remove the hard-baked "cheapness"
heuristic and use TTI directly. Generally NFC intended, but we're using a slightly
different heuristic now so there is a slight test churn.

Test changes:
  * combine-comparisons-by-cse.ll: Removed unneeded branch check.
  * 2014-08-04-muls-it.ll: Test now doesn't branch but emits muleq.
  * coalesce-subregs.ll: Superfluous block check.
  * 2008-01-02-hoist-fp-add.ll: fadd is safe to speculate. Change to udiv.
  * PhiBlockMerge.ll: Superfluous CFG checking code. Main checks still present.
  * select-gep.ll: A variable GEP is not expensive, just TCC_Basic, according to the TTI.

7b91359226 [mips] Merge disassemblers into a single implementation.
Summary:
Currently we have Mips32 and Mips64 disassemblers and this causes the target
triple to affect the disassembly despite all the relevant information being in
the ELF header. These implementations do not need to be separate.

This patch merges them together such that the appropriate tables are checked
for the subtarget (e.g. Mips64 is checked when GP64 is enabled).

caba7561ae [LoopReroll] Introduce the concept of DAGRootSets.
A DAGRootSet models an induction variable being used in a rerollable
loop. For example:

   x[i*3+0] = y1
   x[i*3+1] = y2
   x[i*3+2] = y3

   Base instruction -> i*3
                    +---+----+
                   /    |     \
               ST[y1]  +1     +2  <-- Roots
                        |      |
                      ST[y2] ST[y3]

There may be multiple DAGRootSets, for example:

   x[i*2+0] = ...   (1)
   x[i*2+1] = ...   (1)
   x[i*2+4] = ...   (2)
   x[i*2+5] = ...   (2)
   x[(i+1234)*2+5678] = ... (3)
   x[(i+1234)*2+5679] = ... (3)

This concept is similar to the "Scale" member used previously, but allows
multiple independent sets of roots based off the same induction variable.

8ee1b65836 [PBQP] Cautiously update edge costs in the solver
The NodeMetadata are maintained in an incremental way. When an edge between
2 nodes has its cost updated, in the course of graph reduction for example,
the NodeMetadata need first to have the old edge cost removed, then the new
edge cost added. Only once the NodeMetadata have been fully updated, it
becomes safe to consider promoting the nodes to the
ConservativelyAllocatable or OptimallyReducible sets. Previously, this
promotion was occuring right after the removing the old cost, and this was
breaking the assumption that a ConservativelyAllocatable should not be
spilled.

This patch also adds asserts to:
 - enforces the invariant that a node's reduction can not be downgraded,
 - only not provably allocatable or optimally reducible nodes can be spilled.
