Validate anonymous struct names with namespace
Consider GLSL:
struct { vec4 e; } g;
struct sbbf { vec4 f; };
The struct name validation would fail if user chosen struct name would
clash with a symbol name that ANGLE internally gave to an anonymous
struct.
Fix by importing Name abstraction from MSL backend. A symbol name is
a pair (namespace, string).
Move operator<<(std::ostream &os, const ImmutableString &str)
to sh namespace because that is more natural for operator overloading
name resolution. MSVC works with this.

Revert "Remove few redundant ImmutableString to std::string conversions"
This reverts commit ebb94b807f184f2d36cb0843c429667cd80e0675.
Reason for revert: Needs a different implementation of
std::string::size() to pass C++17 compilers.

- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
"The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by

Avoid mangled name comparisons of 3-parameter functions
The hash values used for looking up built-ins now encode whether the
mangled name contains arrays, structs or interface blocks in its
parameters list. This is written in the most significant bit of the
hash value.
We check this bit at the start of built-in lookup and if the bit is
set we exit early. After that we know that the lookup name doesn't
contain array, struct or interface block parameters.
When we find a hash that matches a hash of a built-in function, we now
know 3 things:
1) the length of the mangled name matches
2) the open parentheses in the mangled name matches
3) the lookup doesn't contain array, struct or block parameters.
Additionally, we have an if statement checking whether the function
name matches. Collisions are only possible with functions that
1) have the same name
2) have the same number of parameters
With these preconditions we can check beforehand whether collisions
are possible for 3-parameter functions. If there are no collisions, we
don't need to compare the full mangled name. This is similar to what
was already being done with functions that had 0 to 2 parameters.
This reduces shader_translator binary size by around 4 KB on Windows.
Besides increased complexity, the tradeoff is that an exhaustive
search of hash values for possible 3-parameter combinations is costly,
so the gen_builtin_functions.py code generation script now takes
around one minute to run on a high-end workstation. Due to this, the
script now exits early if it detects it has already been run with the
same inputs based on a hash value stored in
builtin_symbols_hash_autogen.txt.

Use a specialized hash function for mangled names
The hash values used for looking up built-ins now encode the string
length and the location of parentheses as six-bit values, so that we
don't need to check for these if the hash matches.
This decreases shader_translator binary size on Windows by around 10
KB.

Store symbol names as a ImmutableString
This will enable compile-time initialization of built-in symbols as
well as reducing copying strings.
Most of the code that deals with names is changed to use
ImmutableString where it makes sense to avoid conversions.
The lexer/parser now allocate const char pointers into pool memory
instead of allocating TStrings. These are then converted to
ImmutableString upon entering TParseContext.

This fixes an issue in the original revision of this patch by adding
a operator<< to TInfoSinkBase that takes ImmutableString as a

This also adds ImmutableStringBuilder class, which can be used to
build ImmutableStrings in place without extra allocations if the
maximum length is known in advance.

Add ImmutableString to encapsulate some compiler strings
The new ImmutableString class is intended to be used instead of plain
const char pointers to pool-allocated or static memory.
It has the following advantages over using plain const char pointers:
1. It makes it clear when a string is guaranteed to be safe to pass
around inside the compiler.
2. It can be compared with a comparison operator rather than using
strcmp, which is easier to read.
3. It records the length of the stored string, which enables faster
copies and comparisons in some cases.
4. ImmutableStrings could be implicitly converted from std::strings
when a pool-allocated string is required. This is robust and
convenient.
C++17 has a similar class std::string_view, but our code style doesn't
allow it yet. We also couldn't use it as is if we require properties
1 and 4 from above, but would rather need to inherit or wrap it in a
custom class.
Eventually all current usage of TString could be replaced with
ImmutableString. For now, use it for unmangled built-in names.
