Invalid name - `halhBitsToInt16` instead `halfBitsToInt16` in `glslang/MachineIndependent/Initialize.cpp`

glslang/glslang/MachineIndependent/Initialize.cpp

Lines 4421 to 4424 in 20960a4

	"int16_t halfBitsToInt16(float16_t);"
	"i16vec2 halfBitsToInt16(f16vec2);"
	"i16vec3 halhBitsToInt16(f16vec3);"
	"i16vec4 halfBitsToInt16(f16vec4);"

Description: Typo in a builtin function name: the i16vec3 overload of halfBitsToInt16 is declared as 'halhBitsToInt16' (note 'halh'). The scalar, f16vec2 and f16vec4 overloads are spelled correctly. As a result there is no 'i16vec3 halfBitsToInt16(f16vec3)' prototype, so calling halfBitsToInt16 on an f16vec3 has no matching overload, while a bogus name 'halhBitsToInt16' is registered that is never wired to any operator (relateToOperator only references 'halfBitsToInt16').

Locations:

glslang/MachineIndependent/Initialize.cpp:4423
 4423 |             "i16vec3 halhBitsToInt16(f16vec3);"

Fix: Change 'halhBitsToInt16' to 'halfBitsToInt16' on line 4423.
