teach libanalysis to fold int and fp loads from almost arbitrary
...
non-type-safe constant initializers. This sort of thing happens
quite a bit for 4-byte loads out of string constants, unions,
bitfields, and an interesting endianness check from sqlite, which
is something like this:
const int sqlite3one = 1;
# define SQLITE_BIGENDIAN (*(char *)(&sqlite3one)==0)
# define SQLITE_LITTLEENDIAN (*(char *)(&sqlite3one)==1)
# define SQLITE_UTF16NATIVE (SQLITE_BIGENDIAN?SQLITE_UTF16BE:SQLITE_UTF16LE)
all of these macros now constant fold away.
This implements PR3152 and is based on a patch started by Eli, but heavily
modified and extended.

This address: PR 5277 (Program::Wait is unsafe to call from multiple threads).
Note: If waitpid() turns out to be non-portable, we can add more autoconf magic, or look into
another solution.

triggered by RAUWs and deletes, to support the ExecutionEngine.
