Fix use-of-uninitialized value when RWX memory can't be allocated (PR6701).
...
SELinux doesn't allow 'execmem', returning MAP_FAILED and 'Permission denied'
for mmap or RWX memory. In this case AllocateRWX was returning a MemoryBlock
with uninitialized fields, which sometimes caused crashes.
This patch initializes MemoryBlock fields to 0, so that the RWX-failure check
works.
It doesn't fix the SELinux 'execmem' issues though (the JIT will not work when
SELinux is in enforcing mode).

finally remove the immAllOnesV_bc/immAllZerosV_bc patterns
...
and those derived from them. These are obnoxious because
they were written as: PatLeaf<(bitconvert). Not having an
argument was foiling adding better type checking for operand
count matching up with what was required (in this case,
bitconvert always requires an operand!)

teach tblgen to allow patterns like (add (i32 (bitconvert (i32 GPR))), 4),

transforming it into (add (i32 GPR), 4). This allows us to write type
generic multi patterns and have tblgen automatically drop the bitconvert
in the case when the types align. This allows us to fold an extra load
in the changed testcase.

fix a long standing fixme, which required fixing a bunch of other

issues to get here. We now trim the result type list of the
CompleteMatch or MorphNodeTo operation to be the same size as the
thing we're matching. this means that if you match (add GPR, GPR)
with an instruction that produces a normal result and a flag that
we now trim the result in tblgen instead of having to do it
dynamically. This exposed a bunch of inconsistencies in result
counting that happened to be getting lucky since the days of the
old isel.
