The fuzzer constructs a long, valid nonsense expression
(x+x+x-x+x-x, etc.) which exceeds parse depth. At that point, the token
stream points to a `+` token. The parser attempts to consume a new
statement but stops in `unaryExpression`; this fails again, due to the
max parse-depth, but doesn't consume a token. The parser continues
trying to parse the statement, but stopping in `unaryExpression`, making
no forward progress in an infinite loop.
I've made a couple of changes as a result.
- Exceeding the max parse depth now sets `fEncounteredFatalError`.
- Encountering a fatal error causes block() to immediately halt. This
actually undoes a few of the arbitrary changes from
http://review.skia.org/506463 but not in a bad way.
- `unaryExpression()` now consumes a token before checking parse-depth.
- `structDeclaration()` had a similar issue where it could potentially
fail without consuming any tokens; this is fixed as well.
- Some unnecessarily-nested logic in ternaryExpression() was flattened
while I tried to ensure that it always consumes a token.

std::stringstream has a subtle bug in OS X 10.12. Reading in a too-large
floating point value returns INFINITY but does not set failbit. This
caused SkSL to report a different error message than expected
("floating point value is infinite" instead of "floating-point value
is too large: NNNNN"). We now guard against this case in SkSL::stod by
adding an explicit `isfinite` check.

this was thwarted by VK_NULL_HANDLE which is defined as 0ULL in the
Vulkan headers. It might be possible to enable the warning for a subset

This class will be used to provide thread safe access to various shared
resources in Graphite. Currently the only thing moved onto here is
the SkShaderCodeDictionary. Eventually it will have things like the
pipeline cache on it as well.
The plan is that users will not access this class directly but instead
via a ResourceProvider (see follow on change).

We now use std::string_view throughout. SkStringView.h has been moved to
include/private/ and is only used for our C++20/23 compatibility methods
(starts_with/ends_with/contains).
