- UseWithoutInitialize...: we no longer track variable use-before-init.
- InlineDivideByZero: we no longer constant-fold the result of an
inlined function call into its parent statement.
- Unreachable: we no longer report unreachable statements.
And fixed some minor test-case issues:
- StaticSwitchConditionalBreak: we still check this, but the function
was being dead-stripped before this check could run. Renamed to main.
- OssFuzzXxxxx: these cases no longer report errors, but they are still
valuable as regression tests; moved to `shared/`.

This allows us to remove 100 LOC from the inliner and is very unlikely
to affect any existing benchmark. We don't have any evidence to support
the idea that a one-iteration `for` loop with `continue`-based exits
will be any faster than a standard function call on any existing GPU.
Our fragment processors are generally written to avoid early returns,
in large part to avoid hitting this path.
This drastically impacts BlendEnum.sksl (which can no longer flatten out
a switch over every blend function in SkSL) but is otherwise a wash.

Block::Make always makes a real Block object. This is important because
many callers rely on Blocks specifically; e.g. a function body must be a
scoped Block, nothing else will do.
However, unscoped Blocks are just a collection of Statements and usually
have more flexibility. So, Block::MakeUnscoped is a factory function
that will return the Statement as-is for a single-statement unscoped
Block. For an entirely empty Block, MakeUnscoped returns Nop.

This enables the ternary to be optimized away in code like:
const bool SHINY = true;
color = SHINY ? add_shine(x) : x; // to --> `color = add_shine(x);`
Without constant propagation.
Also, I added a unit test for ternary expression simplification; I
wasn't able to find an existing one.
When the optimization flag is disabled, this CL actually removes the
optimization of `true ? x : y` --> `x` entirely; previously, this
substitution would be made regardless of optimization settings.

This check now runs at function finalization time, before constant
propagation has occurred; this affected the "DeadIfStatement" test.
Our detection isn't smart enough to realize that a loop will run zero
times, so it treats `for` and `while` loops as always running at least
once. This isn't strictly correct, but it actually mirrors how the CFG
implementation works anyway. The only downside is that we would not flag
code like `for (i=0; i<0; ++i) { return x; }` as an error.

Interestingly, this reduces the size of our dehydated data
significantly, because we were storing the result type of the binary
expression explicitly. Now the result type is deduced automatically from
the left and right types by the Make call.

In http://review.skia.org/375776, an optimization was added to the
Inliner, causing it to skip generation of unnecessary temporary
variables. The fuzzer immediately discovered a flaw in this logic: the
"unnecessary" variable was actually used in the rare case that a
function failed to actually return a value. The inliner didn't detect
this case. Of course, this isn't a valid program either, so now we
report the error and cleanly fail.
