d54a6b56a9 Fix a case where the new SROA pass failed to zap dead operands to
selects with a constant condition. This resulted in the operands
remaining live through the SROA rewriter. Most of the time, this just
caused some dead allocas to persist and get zapped by later passes, but
in one case found by Joerg, it caused a crash when we tried to *promote*
the alloca despite it having this dead use. We already have the
mechanisms in place to handle this, just wire select up to them.

c69bdadac9 Add an --enable-backtraces option to configure to determine
whether or not we want to print out backtrace information. Useful
for libraries that don't need backtrace information on a crash.

7b451cf356 Have the DbgVariable "isArtificial" and "isObjectPointer" not
care about it being an argument variable so that we can decide
that captured block and lambda vars that don't happen to
be arguments could be an argument pointer.

Add the object pointer for one case onto the subprogram die.

ced674e470 ARM: Use a dedicated intrinsic for vector bitwise select.
The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

2df8ac84ae Extend -new-coalescer SSA update to handle mapped values as well.
The old-fashioned many-to-one value mapping doesn't always work when
merging vector lanes. A value can map to multiple different values, and
it can even be necessary to insert new PHIs.

When a value number is defined by a copy from a value number that
required SSa update, include the live range of the copied value number
in the SSA update as well. It is not necessarily a copy of the original
value number any longer.
