Previously, tests for the generation of lexical borrow scopes when
-enable-experimental-lexical-lifetimes is passed had been dumped into
the file testing the creation of all borrow scopes. Here, the file
containing tests on general borrow scopes is reverted to its original
state and a new file dedicated to lexical lifetimes is added.
Subsequent tests for SILGen's creation of lexical lifetimes will go into
that new file.
Changed the frontend flag to -enable-experimental-lexical-lifetimes from
-enable-experimental-defined-lifetimes.
Changed the attribute on begin_borrow from [defined] to [lexical].
This is the last part of SILGen conditionalized on EnableSILOwnership being
set. It also (as you can tell from the diff) eliminates a bunch of code from the
tests.

This does not eliminate the entrypoints on SILBuilder yet. I want to do this in
two parts so that it is functionally easier to disentangle changing the APIs
above SILBuilder and changing the underlying instruction itself.

The SILGen testsuite consists of valid Swift code covering most language
features. We use these tests to verify that no unknown nodes are in the
file's libSyntax tree. That way we will (hopefully) catch any future
changes or additions to the language which are not implemented in
libSyntax.
I am going to leave in the infrastructure around this just in case. But there is
no reason to keep this in the tests themselves. I can always just revert this
and I don't think merge conflicts are likely due to previous work I did around
the tooling for this.
Otherwise, the plus_zero_* tests will have plus_zero_* as a module name, causing
massive FileCheck problems.
The reason why I am doing it with the main tests is so that I can use it when
syncing branches/etc.

Use the LValue formal evaluation scope to destroy temporary lvalues that aren't
part of the expression's resulting value.
Disable an old hack that destroyed call site arguments after the call.
This is the first step in cleanup up LValue materialization.
