GLSLstd450SAbs expects a *signed* integer. abs() of an unsigned number is now a no-op.

## 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](https://crbug.com/tint/1150), [tint:1166](https://crbug.com/tint/1166)
|
|
* Identifers beginning with an underscore are now correctly rejected. [tint:1179](https://crbug.com/tint/1179)
|
|
* `abs()` fixed for unsigned integers on SPIR-V backend [tint:1179](https://crbug.com/tint/1194)
