[MIPS64] JNI Compiler: Sign-extend int function arguments

MIPS n64 ABI differs from arm64. Arguments smaller than the 8B stack
slot need to be sign-extended.

Use combination (lw,sd), instead of (lw,sw) for 4B values.

Change fixes software keyboard crash on mips64.

Bug: 21555893

(cherry picked from commit f652d605753f1387e7797461b47116c5dcdf928d)
