Arman Uguray 5f16ed4c58 [sksl] Special-case unary negation on matrix types in MSL/SPIR-V 
MSL does not support the unary "-" operator on matrix types. Similarly
the SPIR-V OpFNegate/OpSNegate operations only work on scalar and vector
type.

* An expression such as "-<mat>" is now transformed to "-1.0 * <mat>" when
generating MSL.
* The same expression now generates a component-wise negation in SPIR-V,
matching what glslang outputs for GLSL.
* A unary "+" is now treated as NOP for MSL, matching the SPIR-V backend.
An expression such as "+<expr>" is now evaluated as "<expr>".
* The shared/Negation.sksl has been moved to folding/ as much of its
contents exercise constant-folding of comparison expressions.
* The shared/UnaryPositiveNegative.sksl test has been extended to
exercise scalar and matrix types.

NOTE: The SPIR-V backend changes have caused a minor re-ordering of SSA
IDs generated when writing out a prefix-expression. The affected gold
files have been updated.
