424dc0f3b0 Add C++ support to Makefile, and proof-of-concept simple.cpp example 
This is a work in progress based on @mikejac's work.

Missing:
* No 'new' operator.
* I don't think STL is currently supported.

bfd38cd1e2 Experimental support for storing const strings in SPI flash or IRAM 
As discussed in #11

Known limitations:
- Only supports l8ui/l16ui
- Unoptimised load routine
- Not called from DoubleExceptionHandler but should be
- Doesn't restore state properly when falling through to fatal exception handler

d685581829 Syscall hander: Fix a3 save address 
(SDK doesn't use syscall exception so bug probably never hit?)

bed6907d22 Exception vector address must be 256 byte aligned 
Not actually a problem with the current linker script as the address is
predetermined there at start of IRAM, but might as well be accurate
about it.

As per advice from @foogod on esp8266-re mailing list:

efc454035c Move all code paths touched by NMI to IRAM 
Prerequisite for calling Cache_Read_Disable() for OTA updates.

Massive thanks due to @foogod and their xtobjdis tool, creating the call
graph of where the wDev_ProcessFiq touched (including in newlib, etc.)
would have otherwise been very painful:

ed7ba52c9a Add exception vectors & low-level handlers 
At the moment these are almost bit-for-bit copies of the vector
behaviour in the RTOS SDK, but hopefully that will start to change.

Progress towards #2
