There are many tests that specify a target triple/CPU flags but no
DataLayout which can lead to IR being generated that has unusual
behaviour. This commit attempts to use the default DataLayout based
on the relevant flags if there is no explicit override on the command
line or in the IR file.
One thing that is not currently possible to differentiate from a missing
datalayout `target datalayout = ""` in the IR file since the current
APIs don't allow detecting this case. If it is considered useful to
support this case (instead of passing "-data-layout=" on the command
line), I can change IR parsers to track whether they have seen such a
directive and change the callback type.

This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

NVPTX/dont-introduce-addrspacecast.ll required manually removing a check for
a bitcast.
AArch64/combine-address-mode.ll required rerunning update_test_checks
Mips required some manual updates due to a CHECK-NEXT coming after a
deleted bitcast.
ARM/sink-addrmode.ll needed one small manual fix.
Excludes one X86 function which needs more attention.
This commit copies existing tests at llvm/Transforms and replaces
'insertelement undef' in those files with 'insertelement poison'.

I don't know anything about debug info, but this seems like more work
should be necessary. This constructs a new IRBuilder and reconstructs
the original divides rather than moving the original.
One problem this has is if a div/rem pair are handled, both end up
with the same debugloc. I'm not sure how to fix this, since this uses
a cache when it sees the same input operands again, which will have
the first instance's location attached.
This should probably be implied for all the speculatable ones. I think
the only ones where this plausibly doesn't apply is s_sendmsghalt and
maybe kill.
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Currently the default C calling convention functions are treated
the same as compute kernels. Make this explicit so the default
calling convention can be changed to a non-kernel.
Converted with perl -pi -e 's/define void/define amdgpu_kernel void/'
on the relevant test directories (and undoing in one place that actually
wanted a non-kernel).
