3a8fed1ac3 Fix mismatched return types for surrogate pairs. 
We've had these backward all this time. The relevant quote is in a
code comment in the implementation, but the first call after
completely decoding a code point that requires a surrogate pair should
return the number of bytes decoded by the most recent call, and the
second call should return -3 (if only C had given those some named
constants that might have been more obviously wrong).

Bug: https://issuetracker.google.com/289419882
Test: Fixed the test, tests run against glibc and musl to confirm

512469a858 Fix wchar tests for zero length conversions. 
Same as the previous change for the uchar tests: the tests are wrong
to match bionic's wrong implementation. Fix the test to encode the bug
for now while I get the tests into good shape, then I'll be back to
fix the bugs and remove the test differences.

686e67d077 Fix wcsto*_l tests for glibc. 
glibc immediately dereferences the locale passed to all wcsto*_l
functions, even if it won't be used, and even if it's
LC_GLOBAL_LOCALE, which isn't a pointer to valid memory.

0e5b89c4bf riscv64: inline raise. 
Not necessary (as demonstrated by the lack of this for x86), but this
saves one stack frame in aborts, which gets you one more useful stack
frame in logs and clustering etc, which improves your chances of finding
your bug.

b08f79af78 riscv64: pass a null argument to ifunc resolvers. 
glibc maintainer Florian Weimer pointed out that glibc passes a null first
argument to riscv64 ifunc resolvers. While not super useful right now,
that does make it much easier to switch to providing arguments in future,
such as my favorite idea of passing a default set of hwprobe key/value
pairs, along with a count of how many pairs.
