Tint changes during Origin Trial

Changes for M97

Breaking Changes

Deprecated modf() and frexp() builtin overloads that take a pointer second parameter have been removed.
Deprecated texture builtin functions that accepted a read access controlled storage texture have been removed.
Storage textures must now only use the write access control.

New Features

any() and all() now support a bool parameter. These simply return the passed argument. tint:1253
Call statements may now include functions that return a value (ignore() is no longer needed).
The interpolate(flat) attribute can now be specified on integral user-defined IO. It will eventually become an error to define integral user-defined IO without this attribute.

Fixes

Swizzling of vec3 types in storage and uniform buffers has been fixed for Metal 1.x. tint:1249

Changes for M95

New Features

The size of an array can now be defined using a non-overridable module-scope constant
The num_workgroups builtin is now supported.

Fixes

Hex floats: now correctly errors when the magnitude is non-zero, and the exponent would cause overflow. tint:1150, tint:1166
Identifiers beginning with an underscore are now correctly rejected. tint:1179
abs() fixed for unsigned integers on SPIR-V backend tint:1179
