Move additional register names to their own lookup, separate from
...
register aliases. Fixes unnecessary renames of clobbers.

add one more case of mismatched input/output constraints.
...
When the mismatch is due to a larger input operand that is
a constant, truncate it down to the size of the output. This
allows us to accept some cases in the linux kernel and elsewhere.
Pedantically speaking, we generate different code than GCC, though
I can't imagine how it would matter:
Clang:
movb $-1, %al
frob %al
GCC:
movl $255, %eax
frob %al

Something's wrong with this test on other platforms. I'll probably need to simplify it later. For now revert.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
