Instead of storing built-ins in a std::unordered_map, we now generate
a series of switch statements using the hash value of the look-up
string. This works similarly to earlier implementation of looking up
unmangled built-ins.

Those built-ins that need to be initialized at run-time are stored as
member variables of TSymbolTable.

This increases compiler init performance significantly, as well as
increasing compiler perf test scores around 1-2%. Binary size is
larger than before though.

With this change we also store only one object per each parameter type

This simplifies code and reduces binary size and compiler memory use.

The translator already prunes no-ops and unreferenced variables, and
this may result in case statements that are followed by nothing.

Since the last case statement in as switch statement must always
contain a statement to be valid GLSL, the translator must not leave
empty case statements in place. They're now being pruned by the
PruneEmptyCases AST transformation. This improves on the earlier
RemoveEmptySwitchStatements AST transformation that did address
empty switch statements but could not remove them if they had a

This implements basic depth/stencil states and clearing.

This also implements "fallback" texture formats in the texture
generation. Fallback formats are those that are chosen at runtime for
replacements for main formats which lack driver support. They are
different from override formats, which are always used because we
assume there is no driver support.

The Vulkan spec only asserts that one of the two of D32 or D24 has
mandatory support. In the case of AMD, D24 is not supported fully, and
we need the fallback format support emulation.

The new mangled name format is as follows:

The first character is a hex digit from 0 to F that encodes vector or
matrix size. For scalars, structs etc. the character is 0.

Then, if it's a struct, the mangled name continues with "{s", followed
by mangled names of fields, and ends with "}".

If it's an interface block, the mangled name continues with "{i",
followed by mangled names of fields, and ends with "}".

If it's anything else, the second alphabetic character encodes the
basic type. Characters are assigned to basic types in the enumeration
order.

If it's an array, the mangled name has a suffix [array_size].
