[XRay][compiler-rt] Add function id utilities for XRay
Summary:
This change allows us to provide users and implementers of XRay handlers
a means of converting XRay function id's to addresses. This, in
combination with the facilities provided in D32695, allows users to find
out:
- How many function id's there are defined in the current binary.
- Get the address of the function associated with this function id.
- Patch only specific functions according to their requirements.
While we don't directly provide symbolization support in XRay, having
the function's address lets users determine this information easily
either during runtime, or offline with tools like 'addr2line'.

[pdb] Don't verify TPI hash values up front.
Verifying the hash values as we are currently doing
results in iterating every type record before the user
even tries to access the first one, and the API user
has no control over, or ability to hook into this
process.
As a result, when the user wants to iterate over types
to print them or index them, this results in a second
iteration over the same list of types. When there's
upwards of 1,000,000 type records, this is obviously
quite undesirable.
This patch raises the verification outside of TpiStream
, and llvm-pdbdump hooks a hash verification visitor
into the normal dumping process. So we still verify
the hash records, but we can do it while not requiring
a second iteration over the type stream.

[PDB] Don't build the entire source file list up front.
I tried to run llvm-pdbdump on a very large (~1.5GB) PDB to
try and identify show-stopping performance problems. This
patch addresses the first such problem.
When loading the DBI stream, before anyone has even tried to
access a single record, we build an in memory map of every
source file for every module. In the particular PDB I was
using, this was over 85 million files. Specifically, the
complexity is O(m*n) where m is the number of modules and
n is the average number of source files (including headers)
per module.
The whole reason for doing this was so that we could have
constant time access to any module and any of its source
file lists. However, we can still get O(1) access to the
source file list for a given module with a simple O(m)
precomputation, and access to the list of modules is
already O(1) anyway.
So this patches reduces the O(m*n) up-front precomputation
to an O(m) one, where n is ~6,500 and n*m is about 85 million
in my pathological test case.

[APInt] Reduce number of allocations involved in multiplying. Reduce worst case multiply size
Currently multiply is implemented in operator*=. Operator* makes a copy and uses operator*= to modify the copy.
Operator*= itself allocates a temporary buffer to hold the multiply result as it computes it. Then copies it to the buffer in *this.
Operator*= attempts to bound the size of the result based on the number of active bits in its inputs. It also has a couple special cases to handle 0 inputs without any memory allocations or multiply operations. The best case is that it calculates a single word regardless of input bit width. The worst case is that it calculates the a 2x input width result and drop the upper bits.
Since operator* uses operator*= it incurs two allocations, one for a copy of *this and one for the temporary allocation. Neither of these allocations are kept after the method operation is done.
The main usage in the backend appears to be ConstantRange::multiply which uses operator* rather than operator*=.
This patch moves the multiply operation to operator* and implements operator*= using it. This avoids the copy in operator*. operator* now allocates a result buffer sized the same width as its inputs no matter what. This buffer will be used as the buffer for the returned APInt. Finally, we reuse tcMultiply to implement the multiply operation. This function is capable of not calculating additional upper words that will be discarded.
This change does lose the special optimizations for the inputs using less words than their size implies. But it also removed the getActiveBits calls from all multiplies. If we think those optimizations are important we could look at providing additional bounds to tcMultiply to limit the computations.

In the alternate macro mode, you can delimit strings with matching angle brackets <..>

1. If an argument begins with '<' and ends with '>'. The argument is considered as a string.
2. Except adding new string mark '<..>', a regular macro behavior is expected.
3. The altmacro cannot affect the regular less/greater behavior.
4. If a comma is present inside an angle brackets it considered as a character and not as a separator.

For certain test cases we spent over 50% of the scop detection time in

MainLoop: Add unit tests
Summary:
This adds a couple of unit tests to the MainLoop class. To get the
kqueue based version of the signal handling passing, I needed to
modify the implementation a bit to make the queue object persistent.
Otherwise, only the signals which are send during the Run call would get
processed, which did not match the ppoll behaviour.
I also took the opportunity to remove the ForEach template functions and
replace them with something more reasonable.
