Remove modifierType/Base from X86 disassembler tables as they are no longer used. Removes ~11.5K from static tables.

[SparcV9]: Use SRL instead of SLL to clear top 32-bits in ctpop:i32. SLL does not clear top 32 bit, only SRL does.

Remove need for MODIFIER_OPCODE in the disassembler tables. AddRegFrms are really more like OrRegFrm so we don't need a difference since we can just mask bits.

Printing rounding control.
Enncoding for EVEX_RC (rounding control).

Second attempt at Removing special form of AddRegFrm used by FP instructions. These instructions can be handled by MRMXr instead.

Revert r198238 and add FP disassembler tests. It didn't work and I didn't realized we had no FP disassembler test cases.

Checking the trailing letter of the mnemonic is insufficient.  Be more thorough
in the scanning of the instruction to ensure that we correctly work with the
predicated mnemonics.

The DPR and SPR register lists are also register lists.  Furthermore, the
registers need not be checked individually since the register type can be
checked via the list kind.  Use that to simplify the logic and fix the incorrect
assertion.

In order to provide compatibility with the GNU assembler, provide aliases for
pre-UAL mnemonics for floating point operations.

This plugs a memory leak in ARM's FastISel by storing the GV in Module so that
it's reclaimed.

[SparcV9] Use separate instruction patterns for 64 bit arithmetic instructions instead of reusing 32 bit instruction patterns.
 This is done to avoid spilling the result of the 64-bit instructions to a 4-byte slot.

[SparcV9] For codegen generated library calls that return float, set inreg flag manually in LowerCall().
 This makes the sparc backend to generate Sparc64 ABI compliant code.

Directive parsers must return false if the target assembler is interested in
handling the directive.  The Error member function returns true always.  Using
the 'return Error()' pattern would incorrectly indicate to the general parser
that the target was not interested in the directive, when in reality it simply
encountered a badly formed directive or some other error.  This corrects the
behaviour to ensure that the parser behaves appropriately.

Schedule more conservatively to account for stalls on floating point
resources and latency. Use the AGU resource to model latency stalls
since it's shared between FP and LD/ST instructions. This might not be
completely accurate but should work well in practice.

Many vector operations never had itineraries. Since the new machine
model was a mapping from existing itinerary classes, we don't have a
model for these. We still want to migrate A9 even though no one has
invested in a complete model, so mark it incomplete to avoid the
scheduler asserting.

vector shift by immedate count (VSHLI/VSRLI/VSRAI) into a build_vector when
the vector in input to the shift is a build_vector of all constants or UNDEFs.

Target specific nodes for packed shifts by immediate count are in
general introduced by function 'getTargetVShiftByConstNode' (in
X86ISelLowering.cpp) when lowering shift operations, SSE/AVX immediate
shift intrinsics and (only in very few cases) SIGN_EXTEND_INREG dag
nodes.

This patch adds extra rules for simplifying vector shifts inside
function 'getTargetVShiftByConstNode'.

Added file test/CodeGen/X86/vec_shift5.ll to verify that packed
shifts by immediate are correctly folded into a build_vector when the
input vector to the shift dag node is a vector of constants or undefs.
