x86: Add -mindirect-branch-register
Add -mindirect-branch-register to force indirect branch via register.
This is implemented by disabling patterns of indirect branch via memory,
similar to TARGET_X32.
-mindirect-branch= and -mfunction-return= tests are updated with
-mno-indirect-branch-register to avoid false test failures when
-mindirect-branch-register is added to RUNTESTFLAGS for "make check".
