Merge r163083 - [GTK] Disable optimizations for JSC that turned out malignant after jsCStack branch merge
https://bugs.webkit.org/show_bug.cgi?id=127909
Reviewed by Carlos Garcia Campos.
* GNUmakefile.am: Disable the -fomit-frame-pointer optimization to achieve proper register usage
in operationCallEval. Disable the -ftree-dce optimization since it is causing additional failures
when using GCC 4.8, possibly due to a bug in the compiler itself.

+# possibly due to a bug in that compiler. See bugs #127777 and #127909 for more information.
