SWDEV-287018 - Remove requiredDump argument from Program::linkLLVMBitcode

Weirdly, the `requiredDump` argument to linkLLVMBitcode was used to enable/disable
the keeping temporary bytecode files (those generated by -save-temps=all) after linking.

This patch removes this argument as there is no obvious benefit from keepeing it
(the user would only rely on -save-temps=all to control this).
