NaCl SDK: don't prune PNaCl biased bitcode from the NaCl SDK build.
Some NaCl users want to use the PNaCl toolchain to build native NaCl
applications that use C++11 and compiler intrinsics. This currently
isn't feasible with the GCC toolchain, and PNaCl doesn't currently offer
all the intrinsics these users want (effectively non-portable inline
assembly). For such a build to work users need libraries that are built
with bitcode biased for their architecture: the front-end knows that it
will target x86-32/x86-64/ARM/MIPS up front and compiles the code
accordingly (e.g. with SSE or NEON support, with certain function
signatures and calling-conventions that follow the platforms'
convention).
This CL increases the size of the NaCl SDK.
The NaCl-side of this CL (building more biased bitcode) is:
