Subject: Tweak the way appendModuleInlineAsm works, so you aren't obliged
X-Git-Tag: android-x86-6.0-r1~1003^2~10528

Tweak the way appendModuleInlineAsm works, so you aren't obliged
to append a newline when using setModuleInlineAsm in case later
someone calls appendModuleInlineAsm - make newline handling fully
automatic.  In case anyone is wondering there is only one user of
appendModuleInlineAsm: the dragonegg plugin.
