* Support for automap options
- Added glslang_shader_options_t with enums for auto map bindings and
auto map locations.
- Added options param to glslang_shader_parse.
- Modified glslang_shader_parse to call appropriate auto map function if
auto map bits are set.
* Refactored auto map for C interface
- Added glslang_shader_set_options to independently set options instead
of being a param on an existing function.
- Added glslang_program_map_io to call mapIO so auto map location
actually works.
* Added support for shifting resource bindings
- Added resource binding shift functions to match C++ interface
* Uncommented preprocessor call that was commented out for debugging
1. The test cases of OpReadClockKHR is invalid. The return type is
unsigned integer rather than signed integer.
2. When SPIR-V decorate or SPIR-V type is specified, we should avoid
auto location mapping because the semantics are totally decided by
SPIR-V tokens.
The signedness of type char is implementation-defined in C++. The
conversion to (signed) int8 currently uses a cast to char, which is
undefined for negative values when the type char is implemented as
unsigned. Thus, fix to cast to "signed char", which has the intended
semantic on all implementations.

There were two implementations of isInf() and isNan(), in Constant.cpp
and in intermOut.cpp. The former only works on little-endian systems,
the latter is a wrapper for library functions and works regardless of
endianness. Move the second version into Common.h and adopt it in both
places. Thereby avoid the duplication and fix for big-endian systems.
A previous commit with the same intent and purpose had missed a required
header for builds on Windows.
On s390x, this fixes the test case
Glsl/CompileToAstTest.FromFile/constFold_frag.

Otherwise this can race with other threads for access to the fields it's
supposed to be initializing/finalizing.
For example, imagine another thread is calling ShInitialize() while the
first thread is calling ShFinalize() - the finalize function would
destroy the state at the same time as the initialize function is trying
to initialize it.
Holding on to the global lock for the entire function prevents all of
these failure modes.
Currently, ShInitialize() and friends call glslang::InitGlobalLock()
which *overwrites* the global mutex. As such, even though it ostensibly
takes a mutex, this function is actually completely thread-unsafe.
Fix it by using pthread_once to ensure the mutex is only initialized
once, and then never again.
Fix#2760.
Implement the optional function select_on_container_copy_contruction to
return a default-contructed allocator for containers that are
copy-constructed. This gives copy-constructed containers a pool
allocator for the current thead.
There may be a similar problem with the copy contructor which takes
allocators of type "Other" but, in practice, there is only one place
where this is being used and the allocators are always the same. (i.e.
executing from the same thread)
1. spirv_execution_mode_id and spirv_decorate_id could support
specialization constants. The original implementation always
assume only normal frontend constants are valid. It is not true.
2. spirv_type donesn't support type_specifier as an option of
spirv_type_parameter. At present, only constant_expression is the
valid option.
