[msan] Fix infinite recursion when _Unwind_Backtrace calls memcpy
Summary:
On PPC64, half the msan tests fail with an infinite recursion through
GetStackTrace like this:
#0 __msan::GetStackTrace

#2 ?? () from /lib64/libgcc_s.so.1
#3 ?? () from /lib64/libgcc_s.so.1
#4 _Unwind_Backtrace

#10 pthread_create@@GLIBC_2.17
#11 __interceptor_pthread_create
#12 main
The problem is that we call _Unwind_Backtrace to get a stack trace; but
_Unwind_Backtrace calls memcpy, which we intercept and try to get
another stack trace.
This patch fixes it in __msan_memcpy by skipping the stack trace if
IsInSymbolizer(). This works because GetStackTrace already creates a
SymbolizerScope to "block reports from our interceptors during
_Unwind_Backtrace".

Switch the new COFF linker's symbol table to use a DenseMap of
StringRefs. This uses the LLVM hashing rather than the standard library
and a closed addressed hash table rather than chaining.
This improves the Windows self-link of LLD by 4.4% (averaged over 10
runs, with well under 1% of variance on each).
There is still some room to improve here. Two things I clearly see in
the profile:
1) This is one of the biggest stress tests for the LLVM hashing code. It
actually consumes something like 3-4% of the link time after the
change.
2) The way that StringRef keys are handled in the DenseMap interface is
pretty suboptimal. We pay the price of checking for empty and
tombstone keys when we could only possibly be looking for a normal
key. But fixing this requires invasive API changes.

AsmPrinter: Document why DIEValueList uses a linked-list, NFC
There are two main reasons why a linked-list makes sense for
`DIEValueList`.
1. We want `DIE` to be on a `BumpPtrAllocator` to improve teardown
efficiency. Making `DIEValueList` array-based would make that much
more complicated.
2. The singly-linked list is fairly memory efficient. The histogram
[1] shows that most DIEs have relatively few values, so we often pay
less than the 2/3-pointer static overhead of a vector. Furthermore,
we don't know ahead of time exactly how many values a `DIE` needs,
so a vector-like scheme will on average over-allocate by ~50%. As
it happens, that's the same memory overhead as the linked list node.

`MachineFunction::print()`. Although I don't have a *particular* user
in mind for this new code, I have hit big slowdowns before when running

someone hits a big slowdown with `print()` statements, they can create a
`ModuleSlotTracker` and send it through. Similarly, adding support to
`Value::dump()` and `Metadata::dump()` should be trivial.

LowerBitSets: Ignore bitset entries that do not directly refer to a global.
It is possible for a global to be substituted with another global of a
different type or a different kind (i.e. an alias) at IR link time. One
example of this scenario is when a Microsoft ABI vtable is substituted with
an alias referring to a larger vtable containing an RTTI reference.
This will cause the global to be RAUW'd with a possibly bitcasted reference
to the other global. This will of course also affect any references to the
global in bitset metadata.
The right way to handle such metadata is simply to ignore it. This is sound
because the linked module should contain another copy of the bitset entries as

[RewriteStatepointsForGC] Generalized vector phi/select handling for base pointers
This change extends the detection of base pointers for vector constructs to handle arbitrary phi and select nodes. The existing non-vector code already handles those, so this is basically just extending the vector special case to be less special cased. It still isn't generalized vector handling since we can't handle arbitrary vector instructions (e.g. shufflevectors), but it's a lot closer.
The general structure of the change is as follows:
* Extend the base defining value relation over a subset of vector instructions and vector typed phi & select instructions.
* Move scalarization from before base pointer rewriting to after base pointer rewriting. The extension of the BDV relation is sufficient to find vector base phis for vector inputs.
* Preserve the existing special case logic for when the base of a vector element is locally obvious. This general idea could be extended to the scalar case as well.

Teach InlineCost to account for a null check which can be folded away
If we have a caller that knows a particular argument can never be null, we can exploit this fact while simplifying values in the inline cost analysis. This has the effect of reducing the cost for inlining when a null check is present in the callee, but the value is known non null in the caller. In particular, any dependent control flow can be discounted from the cost estimate.
Note that we use the parameter attributes at the call site to memoize the analysis within the caller's code. The setting of this attribute is done in InstCombine, the inline cost analysis just consumes it. This is intentional and important because we want the inline cost analysis results to be easily cachable themselves. We're not currently doing so, but initial results on LTO indicate this will quickly become important.

[static analyzer] Analyzer is skipping forward declared C/C++ functions
A patch by Karthik Bhat!
This patch fixes a regression introduced by r224398. Prior to r224398
we were able to analyze the following code in test-include.c and report
a null deref in this case. But post r224398 this analysis is being skipped.
E.g.
// test-include.c
#include "test-include.h"
void test(int * data) {
data = 0;
*data = 1;
}
// test-include.h
void test(int * data);
This patch uses the function body (instead of its declaration) as the location
of the function when deciding if the Decl should be analyzed with path-sensitive
analysis. (Prior to r224398, the call graph was guaranteed to have a definition
when available.)

[LAA] Try to prove non-wrapping of pointers if SCEV cannot
Summary:
Scalar evolution does not propagate the non-wrapping flags to values
that are derived from a non-wrapping induction variable because
the non-wrapping property could be flow-sensitive.
This change is a first attempt to establish the non-wrapping property in
some simple cases. The main idea is to look through the operations
defining the pointer. As long as we arrive to a non-wrapping AddRec via
a small chain of non-wrapping instruction, the pointer should not wrap
either.
I believe that this essentially is what Andy described in
http://article.gmane.org/gmane.comp.compilers.llvm.cvs/220731 as the way
forward.

MIR Serialization: Serialize machine basic block operands.
This commit serializes machine basic block operands. The

This commit also modifies the YAML representation for the
machine basic blocks - a new, required field 'id' is added
to the MBB YAML mapping.
The id is used to resolve the MBB references to the
actual MBBs. And while the name of the MBB can be
included in a MBB reference, this name isn't used to
resolve MBB references - as it's possible that multiple
MBBs will reference the same BB and thus they will have the
same name. If the name is specified, the parser will verify
that it is equal to the name of the MBB with the specified id.
