659d58ceca tint/resolver: Fix BuiltinCall validator nullptr deref
This patch fix a nullptr dereference case in Validator::BuiltinCall,
which check if a no-return-value built-in is called in something other
than call statement. Such call may don't have a statement context at all.

cfe07a1b33 tint/resolver: Shuffle validation code
Restructure the logic so there's less, pointless dynamic casting, and the complexity is reduced.

This alters the order in which variables are validated, hence the change of test.

3a2a279714 Fixup various warnings in Tint which were accidentally suppressed.
When enabling the SPIR-V reader or SPIR-V writer we were suppressing
-Wnewline-eof, -Wold-style-cast, -Wsign-conversion, and -Wweak-vtables
for the `libtint` cmake target and anything that depended on that
target. Because we'd build all readers/ writers by default this caused
us to never hit those warnings.

A recent change to the cmake build sets the Tint backend based on
the Dawn backend. So, there is a much higher chance of not building
the SPIR-V support if you're on a Mac or Windows machine.

This CL removes the suppression of the warnings, adds specific pragmas
into the SPIR-V reader code which imports the SPIRV-Tools headers
and fixes up the warnings which were then firing due to checking
for the new warnings.

f90313396b tint/reader/wgsl: Drop const_expr parsing
The WGSL specification changed so that the enforcing of
initializers being only const-expr is no longer done by the
grammar. This is change is required to allow for 'const' expressions to
reference each other.

e3834c4760 tint/resolver: Resolve 'const' variables
The frontends do not currently emit these, nor do the backends currently
handle them.
