[GTK] Tons of warnings caused by using FORTIFY_SOURCE in an unoptimized build

Reviewed by Martin Robinson.

* Source/autotools/SetupCompilerFlags.m4: only consider enabling FORTIFY_SOURCE if optimizations have
been enabled, since they are required for FORTIFY_SOURCE to work, and enabling FORTIFY_SOURCE unconditionally
generates warnings in newer glibc.

Source/JavaScriptCore:

This is mostly simple - the semantics of deconstruction are already
present in the language, so most of the complexity (if you call it
that) is addition of new AST nodes, and parsing the syntax.

In order to get correct semantics for the parameter lists, FunctionParameters
now needs to store refcounted references to the parameter patterns.
There's also a little work to ensure that variable creation and assignment
occurs in the correct order while the BytecodeGenerator is being constructed.

Reviewed by Geoffrey Garen.

Source/JavaScriptCore:

Currently it's the only opcode that uses m_singletonValue, which is unnecessary. Our current plan is
to remove m_singletonValue so that GenGC can have a simpler story for handling CodeBlocks/FunctionExecutables
during nursery collections.

This patch adds an inline cache for the Structure of to_this so it no longer depends on the ValueProfile's
m_singletonValue. Since nobody uses m_singletonValue now, this patch also removes m_singletonValue from
ValueProfile.

VirtualRegister should be a class
https://bugs.webkit.org/show_bug.cgi?id=121732

Reviewed by Geoffrey Garen.

This is a refactoring change.  Changed VirtualRegister from an enum to a class.
Moved Operands::operandIsArgument(), operandToArgument(), argumentToOperand()
and the similar functions for locals to VirtualRegister class.

This is in preparation for changing the offset for the first local register from
0 to -1.  This is needed since most native calling conventions have the architected
frame pointer (e.g. %rbp for X86) point at the slot that stores the previous frame
pointer.  Local values start below that address.

Add the HashMap as a member variable instead and implement the missing member functions.
