Teach -Wuninitialized to recognize __attribute__((analyzer_noreturn))
for halting the propagation of uninitialized value tracking along
a path.  Unlike __attribute__((noreturn)), this attribute (which
is used by clients of the static analyzer) can be used to annotate
functions that essentially never return, but in rare cares may be
allowed to return for (special) debugging purposes.  This attribute
has been shown in reducing false positives in the static analyzer
by pruning false postives, and is equally applicable here.

Handling this attribute in the CFG itself is another option, but
this is not something all clients (e.g., possibly -Wunreachable-code)
would want to see.

%t.h might be touched by scanners as a hot file on Windows, to fail to remove %.h with single run.

[ms-inline asm] If we have a single asm operand that maps to multiple
MCOperands then iterate over all of then when computing clobbers, inputs and
outputs.

On x86 the 1-to-many mapping is a memory operand that includes a BaseReg(reg),
MemScale(imm), MemIndexReg(reg), an Expr(MCExpr or imm) and a MemSegReg(reg).
Invalid register (Op.getReg() == 0) are not considered when computing clobber.
