28454facbb MSL: Handle packed matrices.
The old method of using a different unpacked matrix type doesn't work
for scalar alignment. It certainly wouldn't have any effect for a square
matrix, since the number of columns and rows are the same. So now we'll
store them as arrays of packed vectors.

e2c95bdcbc MSL: Rewrite how resource indices are fallback-assigned.
We used to use the Binding decoration for this, but this method is
hopelessly broken. If no explicit MSL resource remapping exists, we
remap automatically in a manner which should always "just work".

8c632da461 MSL: Use correct alignment rule for whole structs.
Structs are aligned as you would expect in MSL (maximum member
alignment), and it is not minimum 16 bytes like in std140.

Also rename the dummy "pad" members to a reserved naming scheme.

9b4defe202 CompilerMSL support matrices & arrays in stage-in & stage-out.
Support flattening StorageOutput & StorageInput matrices and arrays.
No longer move matrix & array inputs to separate buffer.
Add separate SPIRFunction::fixup_statements_in & SPIRFunction::fixup_statements_out
instead of just  SPIRFunction::fixup_statements.
Emit SPIRFunction::fixup_statements at beginning of functions.
CompilerMSL track vars_needing_early_declaration.
Pass global output variables as variables to functions that access them.
Sort input structs by location, same as output structs.
Emit struct declarations in order output, input, uniforms.
Regenerate reference shaders to new formats defined by above.

192a882df3 Also unpack regular unary/binary operations on MSL.
Apparently MSL gets confused when you have packed_float3 op float3 ...

607b0d6d42 CompilerMSL support smaller offsets for 3-row row-major matrices.
Support MSL typedefs to declare 3-row row-major matrices as 3-column matrices.
Allow those matrices to be decorated as packed.
Support transposing those matrices when used.
Modify how member alignments are calculated.
