716138ee14 Add option to relax validation of store types.
There are a number of users of spriv-opt that are hitting errors
because of stores with different types.  In general, this is wrong, but,
in these cases, the types are the exact same except for decorations.

The options is "--relax-store-struct", and it can be used with the
validator or the optimizer.

We assume that if layout information is missing it is consistent.  For
example if one struct has a offset of one of its members, and the other
one does not, we will still consider them as being layout compatible.
The problem will be if both struct has and offset decoration for
corresponding members, and the offset are different.

39e25fd8ab Add validation pass for conversion instructions
The pass checks correctness of operands of instruction in opcode range
OpConvertFToU - OpBitset.

Disabled invalid tests

Disabled UConvert validation until Vulkan CTS can catch up.

Add validate_conversion to Android.mk

Also remove duplicate entry in CMakeLists.txt.

0d3b8329a4 Make enums for all currently published extensions
Use the list from the SPIR-V registry page.  Also, capture it as
a string so it's much easier to update via copy-paste.

The validator will accept modules that declare these known
extensions.  However, we might not know about new tokens or
instructions declared in them.  For that we need grammar updates
applied to SPIRV-Headers.

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.

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.

A function definition (an OpFunction with basic blocks) cannot be
decorated with the Import Linkage Type.

dadd5161bb Check strict domination of merge block
If a merge block is reachable, then it must be *strictly* dominated
by its header.  Until now we've allowed the header and the merge
block to be the same.

Also: Use dominates and postdominates methods on BasicBlock to
improve readability.

affbc31849 Making the unit tests more robust.
It is best to check the error messages of unit tests that fail
validation. This will ensure that a validation failure is due to what we
expect and not due to some secondary reason.

9c71c572e5 Check BuiltIn Decoration rules.
When applied to a structure-type member, all members of that structure
type must also be decorated with BuiltIn. (No allowed mixing of built-in
variables and non-built-in variables within a single structure.)

When applied to a structure-type member, that structure type cannot be
contained as a member of another structure type.

There is at most one object per Storage Class that can contain a
structure type containing members decorated with BuiltIn, consumed per
entry-point.

no indexing will be done on the Base pointer/composite.

d75bf5ef03 Validation for decoration rules. Fixes issue #499.
Added a new file where all the decoration validation can be performed.

In this change the SPIRV Spec Section 2.16.1 is implemented:
"It is illegal to initialize an imported variable. This means
that a module-scope OpVariable with initialization value cannot be
marked with the Import Linkage Type."

Also added unit tests.
