35a0695844 Include memory and semantics IDs when iterating over inbound IDs
Fixes Instruction::ForEachInId so it covers
SPV_OPERAND_TYPE_MEMORY_SEMANTICS_ID and SPV_OPERAND_TYPE_SCOPE_ID.
Future proof a bit by using the common spvIsIdType routine.

78338d5ba9 Convert pattern stack from deque to vector, and share it
Also move various vector::reserve calls to State ctor
Negligible perf benefit, but more tidy.

e842c17eb5 Added fixed width encoding to bit_stream
Fixed width encoding is intended to be used for small unsigned integers
when the upper bound is known both to the encoder and the decoder
(for example move-to-front rank).

73e8dac5b9 Added compression tool tools/spirv-markv. Work in progress.
Command line application is located at tools/spirv-markv
API at include/spirv-tools/markv.h

At the moment only very basic compression is implemented, mostly varint.
Scope of supported SPIR-V opcodes is also limited.

Using a simple move-to-front implementation instead of encoding mapped
ids.

Work in progress:
- Does not cover all of SPIR-V
- Does not promise compatibility of compression/decompression across
  different versions of the code.

8d3882a408 Added log(n) move-to-front implementation
The implementation is based on AVL and order statistic tree.

It accepts all kinds of values and the implementation
doesn't expect the behaviour to be consistent with id coding.

Intended by SPIR-V compression algorithms.

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.

ddd40f855b Update capability tests for SPV_KHR_16bit_storage rev 7

applied the fix from Rev 7 of SPV_KHR_16bit_storage:
FPRoundingMode enums are now enabled by the capabilities
introduced by that extension.
