Subject: Improvements around hashing (#1355)

* Fields from upper to lower case in slang-ast-decl.h

* Lower camel field names in slang-ast-stmt.h

* Fix fields in slang-ast-expr.h

* slang-ast-type.h make fields lowerCamel.

* slang-ast-base.h members functions lowerCamel.

* Method names in slang-ast-type.h to lowerCamel.

* GetCanonicalType -> getCanonicalType

* Substitute -> substitute

* Equals -> equals
ToString -> toString

* ParentDecl -> parentDecl
Members -> members

* * Make hash code types explicit
* Use HashCode as return type of GetHashCode
* Added conversion from double to int64_t
* Split Stable from other hash functions

* toHash32/64 to convert a HashCode to the other styles.
GetHashCode32/64 -> getHashCode32/64
GetStableHashCode32/64 -> getStableHashCode32/64

* Other Get/Stable/HashCode32/64 fixes

* GetHashCode -> getHashCode

* Equals -> equals

* CreateCanonicalType -> createCanonicalType

* Catches of polymorphic types should be through references otherwise slicing can occur.

* Fixes for newer verison of gcc.
Fix hashing problem on gcc for Dictionary.

* Another fix for GetHashPos

* Fix signed issue around GetHashPos
