9e5f78f114 Fix the shift patterns, and add test 
Firstly, it adds back the split conditions that I accidentally removed.
Without it the dot insns are never generated, or rather, always split
back to a separate compare instruction.

Secondly, the shift amount should be SI always, not GPR, or GCC will
insert a zero-extend at expand time that it cannot get rid of later.

The test tests whether dot-form instructions are generated for both
"dot" and "dot2" cases, that is, with just a CC output or also a GPR
output; for all four basic shifts, with a register amount or an
immediate amount.  It also tests for superfluous zero-extends.  This
also tests if combine "simplifies" the rotates to right-rotates, which
it shouldn't do anymore.

4ed3092ff8 Only transform rotate to rotatert and v.v. if target has both 
Many targets do not have both rotate and rotatert.  Of the 47 targets
in the tree, 17 have both, 9 have only rotate, 2 have only rotatert, and
19 have neither (this is based on "grep -wil" so it can be slightly off).

rs6000 has only rotate, and mips has only rotatert.  For such targets
simplifying rotate to rotatert and vice versa is not simplifying things
at all.  rs6000 has already way too many rotate patterns (some days it
seems like two thousand, but it is somewhat less in reality still); I
would prefer not to double that again.

So, this patch makes genrecog define HAVE_rotate and HAVE_rotatert if
those RTL codes are mentioned anywhere in the machine description, and
then does the transformation in simplify-rtx.c only if both these flags
are set.

runtime: Don't free tiny blocks in map deletion.

The memory allocator now has a special case for tiny blocks
(smaller than 16 bytes) and they can not be explicitly freed.
