Add an internal switch -minline-thumb1-jumptable to ARM gcc4.6/4.7/4.8
Default is off (ie. no changes of behavior), meaning that gcc may
generate thumb1 jumptable helper calls (eg. __gnu_thumb1_case_sqi) for
switch/case.
Use -minline-thumb1-jumptable to compile code which can be linked
with compiler-rt where helper __gnu_thumb1_case_* doesn't exist.
This is mainly for use to compile NDK gabi++/stlport/libc++ to be
independent of libgcc.a. The only affected binaries are all
in armeabi. ABIs armeabi-v7a and x86/mips aren't affected. Size
differences are
libgabi++_static.a 176286 -> 176538 +0.1%
libstlport_static.a 1406346 -> 1413318 +0.5%
libc++_static.a 2426814 -> 2439074 +0.5%
