This patch updates location lists in various x86 tests to reflect what
instruction referencing produces. There are two flavours of change:
* Not following a register copy immediately, because instruction
referencing can make some slightly smarter decisions,
* Extended ranges, due to having additional information.
The register changes aren't that interesting, it's just a choice between
equally legitimate registers that instr-ref does differently. The extended
ranges are largely due to following stack restores better.

There are various tests that need to be adjusted to test the right
thing with instruction referencing -- usually because the internal
representation of variables is different, sometimes that location lists
change. This patch makes a bunch of tests explicitly not use
instruction referencing, so that a check-llvm test with instruction
referencing on for x86_64 doesn't fail. I'll then convert the tests
to have instr-ref CHECK lines, and similar.

D85085 was pushed earlier but broke tests on mac and win:

Recommitting it after adding mtriple to the llc commands.
Emit correct location lists with basic block sections.
This patch addresses multiple things:
1) It ensures that const_value is emitted when possible with basic block
sections.
2) It emits location lists such that the labels are always within the
section boundary.
3) It fixes a bug when the parameter is first used in a non-entry block
which is in a different section from the entry block.
