c14966b882 Move spv_instruction_t's into vector 
No need to incur another copy here. These guys have embedded vectors
we'd rather not copy.

fcd991f081 Move some temp vectors into parser state 
We don't need to churn the allocations for these every instruction.

23af06c3a3 Validator support for Variable Pointer extension. 
If the variable_pointer extension is used:

* OpLoad's pointer argument may be the result of any of the following:
 * OpSelect
 * OpPhi
 * OpFunctionCall
 * OpPtrAccessChain
 * OpCopyObject
 * OpLoad
 * OpConstantNull

* Return value of a function may be a pointer.

* It is valid to use a pointer as the return value of a function.

* OpStore should allow a variable pointer argument.

11a867f412 Add FlattenDecoration transform 
Add --flatten-decorations to spirv-opt

Flattens decoration groups.  That is, replace OpDecorationGroup
and its uses in OpGroupDecorate and OpGroupMemberDecorate with
ordinary OpDecorate and OpMemberDecorate instructions.

afc60bbebf Fix optimizer on when to write the binary 
The spvtools::Optimizer::Run method should also write the output binary
if optimization succeeds without changes but the output binary vector
does not have exactly the same contents as the input binary.
We have to check both the base pointer of the storage and the size of
the vector

Added a test for this too.

7fe8a57a5b Support SPV_AMD_gcn_shader 
Supported in assembler, disassembler, and binary parser.

The validator does not check SPV_AMD_gcn_shader validation rules
beyond parsing the extension.

Adds generic support for generating instruction tables for vendor
extensions.

Adds generic support for extensions the validator should recognize
(but not check) but which aren't derived from the SPIR-V core
grammar file.
