5f1dd5b86b py/asmarm: Simplify asm_arm_bl_ind to only load via index, not literal. 
The maximum index into mp_fun_table is currently less than 1024 and should
stay that way to keep things efficient for all architectures, so there is
no need to handle loading the pointer directly via a literal in this
function.

2964b41c28 py/asm*: Support assembling code to jump to a register, and get PC+off. 
Useful for position independent code, and implementing state machines.

c0bcf00ed1 py/asm*.c: Remove unnecessary check for num_locals<0 in asm entry func. 
All callers of the asm entry function guarantee that num_locals>=0, so no
need to add an explicit check for it.  Use an assertion instead.

Also, the signature of asm_x86_entry is changed to match the other asm
entry functions.

55f33240f3 all: Use the name MicroPython consistently in comments 
There were several different spellings of MicroPython present in comments,
when there should be only one.

155fdc74d5 py/asm: Remove need for dummy_data when doing initial assembler passes. 
For all but the last pass the assembler only needs to count how much space
is needed for the machine code, it doesn't actually need to emit anything.
The dummy_data just uses unnecessary RAM and without it the code is not
any more complex (and code size does not increase for Thumb and Xtensa
archs).

351424e719 emitnative: Revamp ARM codegen compile after full-arg support refactors. 
The code was apparently broken after 9988618e0e
"py: Implement full func arg passing for native emitter.". This attempts to
propagate those changes to ARM emitter.

d9dc6fff21 py: Allocate memory for assembled code at start of PASS_EMIT. 
Previously was allocating at end of PASS_COMPUTE, and this pass was
being run twice, so memory was being allocated twice.

91cfd414c0 py: Implement native load for viper. 
Viper can now do: ptr8(buf)[0], which loads a byte from a buffer using
machine instructions.

This included a bit of restructuring of the assembler backends.  Note
that the ARM backend is missing a few functions and won't compile.
