[AArch64] Move branch relaxation after bbsection assignment
Because branch relaxation needs to factor in if branches target
a block in the same section or a different one, it needs to run
after the Basic Block Sections / Machine Function Splitting passes.
Because Jump table compression relies on block offsets remaining
fixed after the table is compressed, we must also move the JT
compression pass.
The only tests affected are ones enforcing just the ordering and
the a few that have basic block ids changed because RenumberBlocks
hasn't run yet.

GlobalISel/AArch64: don't optimize away redundant branches at -O0
This patch prevents GlobalISel from optimizing out redundant branch
instructions when compiling without optimizations.
The motivating example is code like the following common pattern in
Swift, where users expect to be able to set a breakpoint on the early
exit:
public func f(b: Bool) {
guard b else {
return // I would like to set a breakpoint here.
}
...
}
The patch modifies two places in GlobalISEL: The first one is in
IRTranslator.cpp where the removal of redundant branches is made
conditional on the optimization level. The second one is in
AArch64InstructionSelector.cpp where an -O0 *only* optimization is
being removed.
Disabling these optimizations increases code size at -O0 by
~8%. However, doing so improves debuggability, and debug builds are
the primary reason why developers compile without optimizations. We
thus concluded that this is the right trade-off.

This tenatively reapplies the patch without modifications, the LLDB
test that has blocked this from landing previously has since been
modified to hopefully no longer be sensitive to this change.
