rs1 doesn't represent a vector arg in this case, so the instructions
were broken for (rs1 % ceil(LMUL)) != 0.

Resolves #1505

fesvr/htif: allow exit on SIGINT.

Currently signal handler would call exit() only on second received
signal, this prevent proper program cleanup.
Instead use signal flag to exit loop.

Add support for setting PMP Granularity over CLI

PMP Granularity is made available as a command line option. The default
value is 4 Bytes. The value can be changed by passing the option
--pmp-granularity=<value> to spike.

Change disasm for vset{i}vli with reserved vtypes to display the reserved bits

Currently there is a bug with the disassembly when vsetivli/vsetvli have invalid vtypes (with reserved bits set). Spike correctly detects this and sets vill, but the disassembler integrated into spike ignores those bits being set and prints the instruction as if they weren't. This makes debugging harder, it looks like an otherwise valid vtype was being rejected and can lead down debugging paths like thinking the vector unit is configured incorrectly.

This commit changes the behaviour so that if these reserved bits are set, it prints out the hex value of the vtype. This is understood by the assembler.
GCC disassembler prints out the decimal value of the vtype in this case, I think that hex value is clearer but I can change it if desired.
