0175008ffa LLL: Fix msg macro with six arguments.
The previous macro used the set built-in in a way incompatible with the current
implementation of set. This commit updates the macro to be more transparent in how it's
working and avoids the use of the set and alloc built-ins.

ff8de3e9fa LLL: Fix for edge case in the create macros.
When (msize) is initially zero the previous create commands failed due to the "lll"
expression overwriting the memory at 0x00. This fix "reserves" memory location 0x00
before calling msize. If msize is already 32 or greater it has no effect.

6cab6b6f49 LLL: Correctly label arguments to ecrecover built-in macro.
(r s v hash) -> (hash v r s) which corresponds to the order that the built-in EVM contract uses.

3299c479b6 LLL: fix handling of "sha3" expression
When PR #2317 changed the EVM opcode from SHA3 to KECCAK256 it broke the `(sha3 loc len)` expression in LLL. This PR fixes things while allowing existing code using the sha3 expression (such as the ENS registrar) to continue to compile.  I.e. both `(keccak256 loc len)` and `(sha3 loc len)` may be used, and the existing related sha3 macros continue to work.

Three end-to-end test cases have been added for kekkac256 and sha3.

c603369a51 Change opcode generated by (panic) to INVALID
EIP-141 ethereum/EIPs#141 has preserved 0xfe as an invalid opcode for aborting EVM execution. The EVM assembler supports this via the INVALID opcode.

The LLL "panic" expression used to generate a jump to an invalid location in order to abort EVM execution.  This change brings "panic" into line with EIP-141 by generating the INVALID opcode instead.

Includes a change to Assembly to allow tags from sub-assemblies to be
used.

Sorry, this get a bit bigger than I thought.
