ARM: use litpools for normal i32 imms when compiling minsize.

With constant-sharing, litpool loads consume 4 + N*2 bytes of code, but
movw/movt pairs consume 8*N. This means litpools are better than movw/movt even
with just one use. Other materialisation strategies can still be better though,
so the logic is a little odd.

R600: Recommit 199842: Add work-around for the CF stack entry HW bug

The unit test is now disabled on non-asserts builds.

The CF stack can be corrupted if you use CF_ALU_PUSH_BEFORE,
CF_ALU_ELSE_AFTER, CF_ALU_BREAK, or CF_ALU_CONTINUE when the number of
sub-entries on the stack is greater than or equal to the stack entry
size and sub-entries modulo 4 is either 0 or 3 (on cedar the bug is
present when number of sub-entries module 8 is either 7 or 0)

We choose to be conservative and always apply the work-around when the
number of sub-enries is greater than or equal to the stack entry size,
so that we can safely over-allocate the stack when we are unsure of the
stack allocation rules.

Remove tail marker when changing an argument to an alloca.

Argument promotion can replace an argument of a call with an alloca. This
requires clearing the tail marker as it is very likely that the callee is now
using an alloca in the caller.

This fixes pr14710.

R600: Unconditionally unroll loops that contain GEPs with alloca pointers

Implement the getUnrollingPreferences() function for
AMDGPUTargetTransformInfo so that loops that do address calculations
on pointers derived from alloca are unconditionally unrolled.

Unrolling these loops makes it more likely that SROA will be able to
eliminate the allocas, which is a big win for R600 since memory
allocated by alloca (private memory) is really slow.

R600: Correctly handle vertex fetch clauses the precede ENDIFs

The control flow finalizer would sometimes use an ALU_POP_AFTER

instruction after it.

R600: Disable the BFE pattern

This pattern uses an SDNodeXForm, which isn't being emitted for some
reason.  I can get it to work by attaching the PatLeaf that has the
XForm to the argument in the output pattern, but this results in an
immediate being used in a register operand, which the backend can't
handle yet.

R600: Remove successive JUMP in AnalyzeBranch when AllowModify is true

This fixes a crash in the OpenCV OpenCL test suite.

There is no lit test for this, because the test would be very large
and could easily be invalidated by changes to the scheduler
or other parts of the compiler.

Add target analysis passes to the codegen pipeline for MCJIT.

This patch adds the target analysis passes (usually TargetTransformInfo) to the
codgen pipeline. We also expose now the AddAnalysisPasses method through the C
API, because the optimizer passes would also benefit from better target-specific
cost models.
