Assign separate SILProfiler instances to stored property initializers
and constructors.
Starting with rdar://39460313, coverage reporting for these constructs
was bundled up into a single SILProfiler uniqued by the NominalTypeDecl.
There are two problems with doing this.
First, the shared SILProfiler is given a fake name that can't be
demangled. That breaks Xcode's reports. Second, the relationship
between SILProfiler and SILFunction is supposed to be 1:1. Having a
shared SILProfiler muddies things a bit and requires extra bookkeeping.

Parsing collection literal expression used to take exponential time
depending on the nesting level of the first element.
Stop using 'parseList()' because using it complicates libSyntax parsing.

* Group tests for profiling instrumentation together, NFC
This will make it easier to test changes to the code coverage logic.
There are a handful of tests which relate to profiling which I have not
moved. These include tests for the driver and for the SIL optimizer. It
makes more sense to keep those tests where they are.
* Rename a test file, NFC
This file tests code coverage of primary files, so I've changed the name
of the file to reflect that.
* Simplify the check lines in a test, NFC
This file tests code coverage of closures. It had several check lines
which obscured the meaning of the test, and its check lines were in a
strange order.
Remove the extra checks and disable -emit-sorted-sil.
