[XRay] Custom event logging intrinsic
This patch introduces an LLVM intrinsic and a target opcode for custom event
logging in XRay. Initially, its use case will be to allow users of XRay to log
some type of string ("poor man's printf"). The target opcode compiles to a noop
sled large enough to enable calling through to a runtime-determined relative
function call. At runtime, when X-Ray is enabled, the sled is replaced by
compiler-rt with a trampoline to the logic for creating the custom log entries.
Future patches will implement the compiler-rt parts and clang-side support for
emitting the IR corresponding to this intrinsic.

[ConstantRange][SimplifyCFG] Add a helper method to allow SimplifyCFG to determine if a ConstantRange has more than 8 elements without requiring an allocation if the ConstantRange is 64-bits wide.
Previously SimplifyCFG used getSetSize which returns an APInt that is 1 bit wider than the ConstantRange's bit width. In the reasonably common case that the ConstantRange is 64-bits wide, this requires returning a 65-bit APInt. APInt's can only store 64-bits without a memory allocation so this is inefficient.
The new method takes the 8 as an input and tells if the range contains more than that many elements without requiring any wider math.

Apply canonicalization rules:
1. Input vectors with no elements selected from can be replaced with undef.
2. If only one input vector is constant it shall be the second one.
This allows constant-folding to cover more ad-hoc simplifications that
were in place and avoid duplication for RHS and LHS checks.
There are more rules we may want to add in the future when we see a
justification. e.g. mask elements that select undef elements can be

Make llvm-rtdlyd -check preserve automatic address mappings made by RuntimeDyld.
Currently llvm-rtdyld in -check mode will map sections to back-to-back 4k
aligned slabs starting at 0x1000. Automatically remapping sections by default is
helpful because it quickly exposes relocation bugs due to use of local addresses
rather than load addresses (these would silently pass if the load address was
not remapped). These mappings can be explicitly overridden on a per-section
basis using llvm-rtdlyd's -map-section option. This patch extends this scheme to
also preserve any mappings made by RuntimeDyld itself. Preserving RuntimeDyld's
automatic mappings allows us to write test cases to verify that these automatic
mappings have been applied.
This will allow the fix in https://reviews.llvm.org/D32899 to be tested with
llvm-rtdyld -check.

Summary:
ConstantRange contains two APInts which can allocate memory if their width is larger than 64-bits. So we shouldn't copy it when we can avoid it.
This changes LVILatticeVal::getConstantRange() to return its internal ConstantRange by reference. This allows many places that just need a ConstantRange reference to avoid making a copy.
Several places now capture the return value of getConstantRange() by reference so they can call methods on it that don't need a new object.
Lastly it adds std::move in one place to capture to move a local ConstantRange into an LVILatticeVal.

[pdb] Don't verify TPI hash values up front.
Verifying the hash values as we are currently doing
results in iterating every type record before the user
even tries to access the first one, and the API user
has no control over, or ability to hook into this
process.
As a result, when the user wants to iterate over types
to print them or index them, this results in a second
iteration over the same list of types. When there's
upwards of 1,000,000 type records, this is obviously
quite undesirable.
This patch raises the verification outside of TpiStream
, and llvm-pdbdump hooks a hash verification visitor
into the normal dumping process. So we still verify
the hash records, but we can do it while not requiring
a second iteration over the type stream.

try and identify show-stopping performance problems. This
patch addresses the first such problem.
When loading the DBI stream, before anyone has even tried to
access a single record, we build an in memory map of every
source file for every module. In the particular PDB I was
using, this was over 85 million files. Specifically, the
complexity is O(m*n) where m is the number of modules and
n is the average number of source files (including headers)
per module.
The whole reason for doing this was so that we could have
constant time access to any module and any of its source
file lists. However, we can still get O(1) access to the
source file list for a given module with a simple O(m)
precomputation, and access to the list of modules is
already O(1) anyway.
So this patches reduces the O(m*n) up-front precomputation
to an O(m) one, where n is ~6,500 and n*m is about 85 million
in my pathological test case.

[llvm-pdbdump] Only build the TypeDatabase if necessary.
Building the type database is expensive, and can take multiple
minutes for large PDBs. But we only need it in certain cases
depending on what command line options are specified. So only
build it when we know we're about to need it.

Remap metadata attached to global variables.
Fix for PR32577.
Global variables may have !associated metadata, which includes a reference to another global. It needs remapping.

During legalization, targets can create Pseudo Instructions with

[JumpThreading] When processing compares, explicitly check that the result type is not a vector rather than check for it being an integer.
Compares always return a scalar integer or vector of integers. isIntegerTy returns false for vectors, but that's not completely obvious. So using isVectorTy is less confusing.
