Reimplement the whole workflow to make that: precise'ness of struct
members won't spread to other non-precise members of the same struct
instance.
Approach:
1. Build the map from symbols to their defining nodes. And for each
object node (StructIndex, DirectIndex, Symbol nodes, etc), generates an
accesschain path. Different AST nodes that indicating a same object
should have the same accesschain path.
2. Along the building phase in step 1, collect the initial set of
'precise' (AST qualifier: 'noContraction') objects' accesschain paths.
3. Start with the initial set of 'precise' accesschain paths, use it as
a worklist, do as the following steps until the worklist is empty:
1) Pop an accesschain path from worklist.
2) Get the symbol part from the accesschain path.
3) Find the defining nodes of that symbol.
4) For each defining node, check whether it is defining a 'precise'
object, or its assignee has nested 'precise' object. Get the
incremental path from assignee to its nested 'precise' object (if
any).
5) Traverse the right side of the defining node, obtain the
accesschain paths of the corresponding involved 'precise' objects.
Update the worklist with those new objects' accesschain paths.
Label involved operations with 'noContraction'.
In each step, whenever we find the parent object of an nested object is
'precise' (has 'noContraction' qualifier), we let the nested object
inherit the 'precise'ness from its parent object.
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
This is according to the expected KHR_vulkan_glsl without floating point.
So, floating-point spec-const operations no longer work, and that's
reflected in the tests.
Much about const or temp is mechanical, about actual declaration,
while much is semantic, about something higher level. This commit
checks every use everywhere, and for the high-level ones, substitutes
an encapsulated version instead.
r26192: Link-time sizing of implicitly-sized arrays and handling of anonymous blocks containing implicitly-sized members. Also changed "__anon" to "anon@" and encapsulated it.
r26240: Solidify the sharing of struct and array information between nodes and variables: A single copy now allows for simultaneously setting array size for all effected nodes and symbols of a given type. This allowed removal of ioArrayNodeResizeList and makes nodes of implicitly sized arrays know the final size.
r26241: Fix g++ issue with wanting non-const iterator.

Also
- uniformly handle EvqConstReadOnly as an input argument in a function, with
isParamInput() and isParamOutput() queries in TQualifier.
- provide a makeTemporary() in TQualifier, for erasing original qualification when making a temp
- provide a makeInternalVariable() call to make a shader variable not seen in the shader source

- moving offset calculations for std140/std430 from reflection to linkValidate.cpp
- applying the offset/align rules on top of std140/std430
- removing caching the structure's number of components (and correcting that this is components, not size)

This included
- encapsulating aggregate constants
- removal of constant-aggregate comparison algorithms, instead using a flattened and direct std::vector comparison
- adding structure type comparison for independently declared structures that still might match types

- don't use [] for map lookups, it can modify the map
- copy up built-in symbols out of shared symbol table levels before modifying them
- enforce shallow vs. deep TType copies
- combine maxArraySize with the array dimensions vector, encapsulate
- remove chaining of array types
