At least since gcc v8, source code with asm volatile won't compile
anymore.

The volatile qualifier anyway is a no-op since asm blocks are implicitly
volatile as written in the documentation[1].

Let's get rid of this redundant qualifier so we can build with newer
GCCs.

The resulting error message is the following (note that there is a
bunch of them):
../3rdparty/javascriptcore/JavaScriptCore/jit/JITStubs.cpp:617:5: error: expected '(' before 'volatile'
asm volatile (
 ^~~~~~~~
 (
../3rdparty/javascriptcore/JavaScriptCore/jit/JITStubs.cpp:618:1: error: expected unqualified-id before string constant
".text\n"
^~~~~~~~~
../3rdparty/javascriptcore/JavaScriptCore/jit/JITStubs.cpp:617:15: error: expected ')' before string constant
asm volatile (
	  ~^
	   )
".text\n"
~~~~~~~~~
