Jim Grosbach f0d25117c6 ARM VFP add encoding of the bitcount to fixed-point<-->floating point. insns.
The value from the operands isn't right yet, but we weren't encoding it at
all previously. The parser needs to twiddle the values when building the
instruction.

Jim Grosbach 12ccf45bbb ARM assembler should accept shift-by-zero for any shifted-immediate operand.
Just treat it as-if the shift wasn't there at all. 'as' compatibility.

Jim Grosbach 1152cc0cad ARM asm parser should be more lenient w/ .thumb_func directive.
Rather than require the symbol to be explicitly an argument of the directive,
allow it to look ahead and grab the symbol from the next non-whitespace
line.

Jakob Stoklund Olesen b95c102c2f Heed spill slot alignment on ARM.
Use the spill slot alignment as well as the local variable alignment to
determine when the stack needs to be realigned. This works now that the
ARM target can always realign the stack by using a base pointer.

Still respect the ARMBaseRegisterInfo::canRealignStack() function
vetoing a realigned stack.  Don't use aligned spill code in that case.

Bob Wilson 75f12cc3fe Mark ARM eh_sjlj_dispatchsetup as clobbering all registers. Radar 10567930.
We used to rely on the *eh_sjlj_setjmp instructions to mark that a function
with setjmp/longjmp exception handling clobbers all the registers.  But with
the recent reorganization of ARM EH, those eh_sjlj_setjmp instructions are
expanded away earlier, before PEI can see them to determine what registers to
save and restore.  Mark the dispatchsetup instruction in the same way, since
that instruction cannot be expanded early.  This also more accurately reflects
when the registers are clobbered.

Jim Grosbach e2ca9e5b5f ARM assembly shifts by zero should be plain 'mov' instructions.
"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's
not strictly legal UAL syntax. It's a common extension and the friendly
thing to do.
