Don't generate unnecessary signed ConstantRange during multiply.  NFC

r231483 taught ConstantRange::multiply to be clever about signed vs unsigned ranges. For example, an unsigned range could be full-set while the signed range is more specific than that.

In looking at the allocations trace for LTO'ing verify-uselistorder (see r236629 for details), millions of allocations are from APInt, many of which come from ConstantRange's.

This change tries to avoid some (3.2 million) allocations by returning the unsigned range if its suitable. The checks here are that it should not be a wrapping range, and should be positive. That should be enough to check for ranges such as [1, 10) which the signed range will be equal to, if we were to calculate it.

[RewriteStatepointsForGC] All constant should have null base pointer

Currently we consider that each constant has itself as a base value. I.e "base(const) = const".
This introduces couple of problems when we are trying to avoid reporting constants in statepoint live sets:

1. When querying "base( phi(const1, const2) )" we will get "phi(const1, const2)" as a base pointer. Since
   it's not a constant we will record it in a stack map. However on practice we don't want this to happen
   (constant are never relocated).
2. base( phi(const, gc ptr) ) = phi( const, base(gc ptr) ). This particular case imposes challenge on our
   runtime - we don't expect to see constant base pointers other than null. This problems can be avoided
   by treating all constant as if they were derived from null pointer base. I.e in a first case we will
   not include constant pointer in a stack map at all. In a second case we will get "phi(null, base(gc ptr))"
   as a base pointer which is a lot more convenient.

traditional data structures to iterate and manipulate these
records, we need the memory to be contiguous.

As a result of this, we were using roughly twice as much memory
as the file size of the PDB, because every stream was copied
out and re-stitched together contiguously.

This patch addresses this by improving the MappedBlockStream
to allocate from a BumpPtrAllocator only when a read requires
a discontiguous read.  Furthermore, it introduces some data
structures backed by a stream which can iterate over both
fixed and variable length records of a PDB.  Since everything
is backed by a stream and not a buffer, we can read almost
everything from the PDB with zero copies.

PR26055: Speed up LiveDebugValues::transferDebugValue()

This patch builds upon r270776 and speeds up
LiveDebugValues::transferDebugValue() by adding an index that maps each
DebugVariable to its open VarLoc.

The transferDebugValue() function needs to close all open ranges for a
given DebugVariable. Iterating over the set bits of OpenRanges is
prohibitively slow in practice. I experimented with using the sorted map
of VarLocs in the UniqueVector to iterate only over the range of VarLocs
with a given DebugVariable, but the binary search turned out to be even
more expensive than just iterating over the set bits in OpenRanges.
Instead, this patch exploits the fact that there can only be one open
location for each DebugVariable and redundantly stores this location in a
DenseMap.

This patch brings the time spent in the LiveDebugValues pass down to an
almost neglectiable amount.
