David Majnemer 6cf6c05322 InstCombine: Stop two transforms dueling
InstCombineMulDivRem has:
// Canonicalize (X+C1)*CI -> X*CI+C1*CI.

InstCombineAddSub has:
// W*X + Y*Z --> W * (X+Z)  iff W == Y

These two transforms could fight with each other if C1*CI would not fold
away to something simpler than a ConstantExpr mul.

The InstCombineMulDivRem transform only acted on ConstantInts until
r199602 when it was changed to operate on all Constants in order to
let it fire on ConstantVectors.

To fix this, make this transform more careful by checking to see if we
actually folded away C1*CI.

This fixes PR20079.

Zachary Turner 62ce4e88fd Replace Execution Engine's mutex with std::recursive_mutex.
This change has a bit of a trickle down effect due to the fact that
there are a number of derived implementations of ExecutionEngine,
and that the mutex is not tightly encapsulated so is used by other
classes directly.

Greg Clayton 9e42e92e43 Don't allow multiple line entries with the same address to exist sequentially.
The compiler, when JIT'ing code, can emit illegal DWARF line tables (address is line table sequences must increase). This changes fixes that issue by replacing previous line entries whose start address is the same with the new line entry to avoid having multiple line entries with the same address. Since the address range of lines entries is determined by the delta between the current and next line entry, this shouldn't cause any issues.

Diego Novillo b2ad56effc Simply test for available locations in optimization remarks.
When emitting optimization remarks, we test for the presence of
instruction locations by testing for a valid llvm.dbg.cu annotation.
This is slightly inefficient because we can simply ask whether the
debug location we have is known or not.

Additionally, if my current plan works, I will need to remove the
llvm.dbg.cu annotation from the IL (or prevent it from being generated)
when -Rpass is used without -g.  In those cases, we'll want to generate
line tables but we will want to prevent code generation from emitting
DWARF code for them.

Tested on x86_64.

Ulrich Weigand f460d69ada [PowerPC] Remove unnecessary load of r12 in indirect call
When looking at the 64-bit SVR4 indirect call sequence, I noticed
an unnecessary load of r12.  And indeed the code says:

  // R12 must contain the address of an indirect callee. 

But this is not correct; in the 64-bit SVR4 (ELFv1) ABI, there is
no need to load r12 at this point.  It seems this code and comment
is a remnant of code originally shared with the Darwin ABI ...

This patch simply removes the unnecessary load.
