Jakob Stoklund Olesen 83d5d19aea Special case Recycler::clear(BumpPtrAllocator). 
A BumpPtrAllocator has an empty Deallocate() method, but
Recycler::clear() would still call it for every single object ever
allocated, bringing all those objects into cache. As a bonus,
iplist::remove() will also write to the Prev/Next pointers on all the
objects, so all those cache lines have to be written back to RAM before
the pages are given back to the OS.

Stop wasting time and memory bandwith by using the new
clearAndLeakUnsafely() function to jettison all the recycled objects.

Jakob Stoklund Olesen 4ccabc1da9 Add an iplist::clearAndLeakNodesUnsafely() function. 
The iplist::clear() function can be quite expensive because it traverses
the entire list, calling deleteNode() and removeNodeFromList() on each
element. If node destruction and deallocation can be handled some other
way, clearAndLeakNodesUnsafely() can be used to jettison all nodes
without bringing them into cache.

The function name is meant to be ominous.

Paul Redmond 874f01e956 Do not vectorize loops with subtraction reductions 
Since subtraction does not commute the loop vectorizer incorrectly vectorizes
reductions such as x = A[i] - x.

Preston Gurd e36b685a94 The current Intel Atom microarchitecture has a feature whereby when a function 
returns early then it is slightly faster to execute a sequence of NOP
instructions to wait until the return address is ready,
as opposed to simply stalling on the ret instruction
until the return address is ready.

When compiling for X86 Atom only, this patch will run a pass, called
"X86PadShortFunction" which will add NOP instructions where less than four
cycles elapse between function entry and return.

It includes tests.

Patch by Andy Zhang.

Manman Ren fe5a61edbe Memory Dependence Analysis: fix a miscompile that uses DT to approxmiate the 
reachablity.

We conservatively approximate the reachability analysis by saying it is not
reachable if there is a single path starting from "From" and the path does not
reach "To".

Adhemerval Zanella 9b0b781395 PowerPC: Fix eh_frame relocation for PIC 
This patch fixes the PPC eh_frame definitions for the personality and 
frame unwinding for PIC objects. It makes PIC build correctly creates
relative relocations in the '.rela.eh_frame' segments and thus avoiding
a text relocation that generates a DT_TEXTREL segments in link phase.

This is a possible regression of moving to using ImplicitNullDerefEvent.

plumbing in ImplicitNullDerefEvent.  This is just a stop gap fix.
